2023-2 Mertol Tüfekci, Vehbi Öztekin, İnci Pir, Murat Alioğlu, Can Dikicioğlu, Adnan Dikicioğlu, Ekrem Tüfekci Low strain rate mechanical performance of balsa wood and carbon fibre-epoxy-balsa sandwich structures https://doi.org/10.1016/j.jcomc.2023.100416 The focus of this study is the experimental assessment of the mechanical behaviour of balsa wood and its sandwich structures, where balsa serves as the core, supported by carbon fibre-epoxy skin layers. A comprehensive characterisation is conducted on the mechanical behaviour of balsa wood and carbon fibre-epoxy balsa core sandwich structures subjected to a range of low strain rates. Initially, the study undertakes a consistent procedure for sample preparation. Subsequently, the characterisation of the manufactured composite structures is performed experimentally. A stereo microscope is employed for a detailed visual inspection of the internal structure of the balsa wood and the sandwich structures. Furthermore, the mechanical characterisation is carried out with three-point bending tests at a range of strain rates from 0.1 % to 6 % strain per minute. This research reveals key findings about balsa wood and its sandwich structures, highlighting their performance and their sensitivity even under low strain rates.
2023-2 Seren Acarer, İnci Pir, Mertol Tüfekci, Tuǧba Erkoç, Sevgi Güneş Durak, Vehbi Öztekin, Güler Türkoǧlu Demirkol, Mehmet Şükrü Özçoban, Tuba Yelda Temelli Çoban, Selva Ćavuş, and Neşe Tüfekci Halloysite Nanotube-Enhanced Polyacrylonitrile Ultrafiltration Membranes: Fabrication, Characterization, and Performance Evaluation https://doi.org/10.1021/acsomega.3c03655 This research focuses on the production and characterization of pristine polyacrylonitrile (PAN) as well as halloysite nanotube (HNT)-doped PAN ultrafiltration (UF) membranes via the phase inversion technique. Membranes containing 0.1, 0.5, and 1% wt HNT in 16% wt PAN are fabricated, and their chemical compositions are examined using Fourier transform infrared (FTIR) spectroscopy. Scanning electron microscopy (SEM) is utilized to characterize the membranes’ surface and cross-sectional morphologies. Atomic force microscopy (AFM) is employed to assess the roughness of the PAN/HNT membrane. Thermal characterization is conducted using thermal gravimetric analysis (TGA) and differential thermal analysis (DTA), while contact angle and water content measurements reveal the hydrophilic/hydrophobic properties. The pure water flux (PWF) performance of the porous UF water filtration membranes is evaluated at 3 bar, with porosity and mean pore size calculations. The iron (Fe), manganese (Mn), and total organic carbon (TOC) removal efficiencies of PAN/HNT membranes from dam water are examined, and the surfaces of fouled membranes are investigated by using SEM post-treatment. Mechanical characterization encompasses tensile testing, the Mori–Tanaka homogenization approach, and finite element analysis. The findings offer valuable insights into the impact of HNT doping on PAN membrane characteristics and performance, which will inform future membrane development initiatives.

In this study, the effects of polyvinylpyrrolidone (PVP), the impact of different amounts (0.5% and 1% wt.) of cellulose nanofibril (CNF), and the combined effects of PVP-CNF on the properties/performance of the polyethersulfone-based (PES-based) membrane are investigated. All PES-based ultrafiltration (UF) membranes are manufactured employing the phase inversion method and characterised via Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and the relevant techniques to determine the properties, including porosity, mean pore size, contact angle, water content, and pure water flux tests. Furthermore, the thermal properties of the prepared membranes are investigated using thermal gravimetric analysis (TGA) and differential thermal analysis (DTA) techniques. Experimental and numerical methods are applied for the mechanical characterisation of prepared membranes. For the experimental process, tensile tests under dry and wet conditions are conducted. The finite element (FE) method and Mori-Tanaka mean-field homogenisation are used as numerical methods to provide more detailed knowledge of membrane mechanics.
2023-2 Ömer Faruk Argın, Ozan Kaya, Zeki Yağız Bayraktaroğlu, Şeniz Ertuğrul A Compliant Teleoperation System by Utilizing Haptic Guidance and Series Elastic Actuator-Based Gripper https://doi.org/10.1115/1.4055570 This article introduces a haptic-guided teleoperation framework using a series elastic actuator (SEA)-based compliant gripper. The proposed teleoperation system involves one local haptic device, one layer of virtual reality, and one remote industrial manipulator with a compliant gripper. The overall compliance of the teleoperation is distributed between the software and hardware components of the bilateral loop. On the one hand, the implemented haptic guidance is based on an elementary coupling model uniquely defined and established for all interactions among the user, remote manipulator, and virtual interface. On the other hand, the manipulator operating in the remote environment is equipped with a novel compliant gripper based on series elastic actuators, providing passive compliance at the interactions with the environment. Introducing the gripper into the haptic loop is expected to compensate for disturbances due to inaccurate modeling and/or unmodeled dynamics of the remote environment and external effects. The teleoperation system is implemented for manipulation and tracking tasks and tested with different users. Experimental results show that the haptic guidance and the compliant gripper together significantly improve the teleoperation performances in terms of transparency

2023-2 Ayhan Hacıoğlu, Adem Candaş, Cemal Baykara Large Deflections of Functionally Graded Nonlinearly Elastic Cantilever Beams doi.org/10.1115/1.4056034 Uses of functionally graded materials (FGMs) are increasing owing to recent development in manufacturing technologies. Large deflection of beams that made of nonlinearly elastic, Ludwick’s type of material, and also FGMs has received considerable critical attention during recent years. However, the precise effect of a number of laminae on both vertical and horizontal deflection of the beam in the finite element analysis (FEA) is unknown. Here, we examined the large deflections of a cantilever beam that was subjected to various loading conditions and made of nonlinearly elastic, modified Ludwick’s type of material using FEA. The direction-dependent material properties in the functionally graded material and nonlinearity from modified Ludwick’s law are combined in the analysis using Marlow’s material model. Our results show that the gradient function and the number of laminae have significant effects on normal stress distribution along the horizontal axis and both vertical and horizontal deflection of the beam
2023-2 Adem Candaş, Erkan Öterkuş, Cevat Erdem İmrak Peridynamic simulation of dynamic fracture in functionally graded materials subjected to impact load doi.org/10.1007/s00366-021-01540-2 Dynamic crack propagation assessment in functionally graded materials (FGMs) with micro-cracks is accomplished using bond-based Peridynamics (PD). The dynamic fracture behaviour of various FGMs’ material models is studied in Kalthoff– Winkler experiment. Dynamic crack growth predictions and associated material damage of the specimen under dynamic loading conditions are considered. The effect of micro-cracks near macro-crack tips on the toughening mechanism is evalu- ated in terms of crack propagation velocities. Stochastically pre-located micro-cracks are modelled to obtain the toughening effect in the material. In addition, the velocities and time required for fracture are compared in different FGM cases. It is frankly found that if a crack propagates in the harder region of the specimen, velocities decrease and toughness increase in contrast to the softer region. Furthermore, micro-cracks around a macro-crack decelerate the crack propagation and enhance toughening mechanism in FGM body depending on gradation of material properties.

2023-2 Annamaria Pau, Uğurcan Eroğlu Identification of Damage in Beams by Modal Curvatures Using Acoustic Beamformers 10.3390/app131910557  This paper presents an approach to damage identification in beams by modal curvatures based on the use of beamforming algorithms. These processors have been successfully used in acoustics for the last thirty years to solve the inverse problems encountered in source recognition and image reconstruction, based on ultrasonic waves. In addition, beamformers apply to a broader range of problems in which the forward solutions are computable and measurable. This especially concerns the field of structural vibrations, where the use of such estimators has not received attention to date. In this paper, modal curvatures will play the role of replica vectors of the imaging field. The choice to use modal curvatures is motivated by means of numerical studies and experimental tests on a steel beam. Furthermore, we compare the performance of the Bartlett and minimum variance distortionless response (MVDR) beamformers with an estimator based on the simple minimization of the difference between model and measured data. The results suggest that the application of the MVDR beamformer is highly effective, especially in cases of slight damage between two sensors. MVDR enables both damage localization and quantification
2023-2 Annamaria Pau, Uğurcan Eroğlu The minimum variance distortionless response beamformer for damage identification using modal curvatures 10.21741/9781644902431-74 This study presents a damage identification procedure in beams based on the use of beamforming algorithms, which are mostly utilized in inverse problems of source identification and image reconstruction. We choose the modal curvatures as observed quantities and compare the performance of the Bartlett beamformer, minimum variance distortionless response (MVDR) processor, and of a conventional objective function based on the modal curvatures. By means of a set of experiments, we show that the MVDR processor can overcome some of the difficulties encountered with other estimators, especially in cases of slight damage, or damage located between two sensors.
2023-2 Uğurcan Eroğlu, Giuseppe Ruta Perturbations for vibration of nano-beams of local/nonlocal mixture 10.21741/9781644902431-100 Here we extend the perturbation approach, previously presented in the literature for Eringen’s two-phase local/nonlocal mixture model, to free vibration of purely flexible beams. In particular, we expand the eigenvalues and the eigenvectors into power series of the fraction coefficient of the non-local material response up to 2nd order. We show that the family of 0th order bending couples satisfy the natural and essential boundary conditions of the 1st order; hence, the 1st order solution can conveniently be constructed using the eigenspace of the 0th order with no necessity of additional conditions. We obtain the condition of solvability that provides the incremental eigenvalue in closed form. We further demonstrate that the 1st order increment of the eigenvalue is always negative, providing the well-known softening effect of long-range interactions among the material points of a continuum modelled with Eringen’s theory. We examine a simply supported beam as a benchmark problem and present the incremental eigenvalues in closed form.

2023-2 Hilal Koc, Ekrem Tufekci A novel approach of bending behavior of carbon nanotubes by combining the effects of higher-order boundary conditions and coupling through doublet mechanics https://doi.org/10.1080/15376494.2023.2263767 This article presents the bending behavior of carbon nanotubes (CNTs) based on doublet mechanics (DM) and Euler–Bernoulli beam theory to analyze how deflection changes with higher-order boundary conditions and the coupling, which have not been previously investigated. The governing equations and associated boundary conditions are obtained using the principle of minimum potential. Numerical solutions show an important effect of higher-order boundary conditions on the deflection of cantilever CNTs, unlike simply supported CNTs. A paradox in which DM shows a stiffening behavior for cantilever CNTs is resolved using higher-order boundary conditions. The coupling significantly effects the bending behavior of armchair CNTs.

2023-2 E. Soylemez Capillary force method to improve the green density of binder jet additive manufacturing https://doi.org/10.21595/amr.2023.23275 This study investigates the impact of capillary adhesion force on the green part density in metal powder binder jetting 3D printing. Gas atomized Co-Cr-Mo, SS316L, and pure Cu powders were used to print various samples. The printed samples were then treated with water, 1-Hexanol, and n-Amyl alcohol vapor for 24 hours to nucleate capillary bridges between particles and shrink samples uniformly. The volume change was calculated for each sample, and up to –3.1 % volume change was observed. The proposed method can be used to improve green part densities directly on printed parts before sintering.
2023-2 C.G. Akagündüz, and E. Soylemez Optimization of Laser Direct Structuring Process Parameters for Material Extrusion of Polycarbonate https://doi.org/10.1002/adem.202300907 Laser direct structuring (LDS) is critical in the integration of circuits onto 3D-shaped plastic parts, such as antennas and radio frequency components. The LDS process encompasses three stages: deposition of 3D parts, laser structuring, and metallization. While laser-direct structurable parts have been manufactured through plastic injection molding, material extrusion (MEX) is a favored additive manufacturing process for economic low-volume production and fast prototyping advantages. Although injection-molded LDS literature is available, 3D-printed laser-direct structured components merit further investigation. This study focuses on the MEX of catalyst-loaded polycarbonate (PC) parts and its LDS process. The parameters from the nanosecond fiber laser, including scan speed, power, and frequency, are thoroughly analyzed to understand the surface property changes and metallization performance of the printed PC parts. The single scan track width, which corresponds to the accuracy of conductive path width and metallization thickness, is employed to elucidate the findings. A process map is built to keep the track width constant aimed at enhancing the uniform metallization of intricate components. Thresholds are established, identifying a minimum track width of 22.1 μm and metallization thickness of 2.5 μm. These delineate clusters of process parameters that yield conductivity levels suitable for various applications.

ITU Faculty of Mechanical Engineering

mkn-hakkimizda

ITU Faculty of Mechanical Engineering takes pride in having close to 100 years of Mechanical Engineering tradition, and has currently 33 Professors, 12 Associate Professors, 24 Assistant Professors and 15 Lecturers as Faculty members. At present, we have over 2000 undergraduate students, all of which were selected among the top ~0.5% of the ~2.3 million students taking the nationwide university entrance exam annually.

Founded in 1933, the Faculty of Mechanical Engineering received its current name in 1944. With the university reform in 1933, the Institute of Electricity and Machines of the Istanbul University was replaced by the Electro-Mechanic Department; and by doing so our Mechanical Engineering education, which still continues, began 87 years ago. 11 years later in 1944, the name of the institution was changed to Istanbul Technical University and under it a separate school/college of Mechanical Engineering was founded with the current name: “Faculty of Mechanical Engineering“.

Our faculty is one of the oldest institutions in our country that carries out education and research activities in the field of mechanical engineering. The different engineering branches it hosts have developed and become a faculty. in 1969; Faculty of Naval Architecture and Marine Sciences, in 1983; The Faculty of Textile Technologies and Design and the Faculty of Aeronautics and Astronautics gained their independent status.In the first years, the Mining Engineering department, which was part of the basic sciences and general engineering courses instruct within the scope of the Faculty of Mechanical Engineering, became an independent faculty in 1953.

ITU Faculty of Mechanical Engineering performs research and education in the design, development and production planning of all types of mechanical and energy transformation systems. Our 75 Faculty members are performing research and development in a wide range of areas related to both immediate needs of the industry and also cutting edge science for future technologies and applications. Our research areas include, but not limited to, Automotive Industry, Petrochemical Industry, Robotics, Textile Industry, Defense Industry, Reverse Engineering, Clean Energy, Renewable Energy, Underground Gasification, MEMS, Nanotechnology, Pharmaceutics, and Biomolecular Engineering.

With its gorgeous Ottoman era building providing extensive lab space, massive laboratory and research investment performed in the past 87 years, and the recent addition of the 1500 m2 big Dr. Keskin Keser student lab building, the Faculty of Mechanical Engineering has one of the most extensive educational and research laboratories in Turkey and provides its students with top quality Mechanical Engineering education in a gorgeous historical building located at a prime location in the very heart of Istanbul.
