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. |

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. |

Characterisation and modelling the mechanics of cellulose nanofibril
added polyethersulfone ultrafiltration membranes |
https://doi.org/10.1016/j.heliyon.2023.e13086 |
The performance of the membranes
can be improved by adding the appropriate amount of nanomaterials to the
polymeric membranes that can be used for water/wastewater treatment. 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. |

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 |

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 |

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. |

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 |

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. |

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. |

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. |

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. |

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. |

https://doi.org/10.47480/isibted.1391429 |
An analytical method has been
proposed for the sublimation from a hemispherical ice sample as a combination
of the models for the spherical and circular flat surfaces. The sublimation
rate calculated by this new analytical method has been compared to the
results from the weighing experiments and visualizations where the
sublimation over time was measured by processing a series of images of ice
cubes. |
