The Nonlinear Visco‐Hyperelastic Damage Mechanics of Individual Electrospun Polycaprolactone Fibers: Experiments and Modeling

Advanced Engineering Materials, EarlyView.
This study investigates the complex mechanics of individual electrospun polycaprolactone fibers under small and large strains. Combining experiments with a visco‐hyperelastic damage model, this work reveals and quantifies these fibers’ nonlinear behavior, including strain‐stiffening, viscoelasticity, and damage.

Handwriting expertise reliability: A review

Journal of Forensic Science and Medicine, 2019
Handwriting expertise, as a form of forensic evidence, was once considered by most courts under the Anglo-American law system to be infallible, but this position was significantly challenged by the Daubert case (1993) and further by the President's ...

Mechanical and Microstructural Effects of ZrO2 Nanoparticles in Fe20Cr Oxide Dispersion‐Strengthened Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
The influence of oxide nanoparticle synthesis route and concentration on microstructure and high‐temperature performance of additively manufactured oxide dispersion‐strengthened steels is investigated. Comparing laser‐generated and chemically synthesized ZrO2 nanoparticles, the study reveals how dispersion quality, crystal structure and particle size ...

Quality Enhancement of Laser Powder‐Bed Fusion Parts by Acoustically Assisted Additive Manufacturing by Laser Powder‐Bed Fusion and its Application to Lattice Structures

Advanced Engineering Materials, EarlyView.
Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.

The VITEWRITE Model of Handwriting Production [PDF]

, 1993
This article describes the VITEWRITE model for generating handwriting movements. The model consists of a sequential controller, or motor program, that interacts with a trajectory generator to move a hand with redundant degrees of freedom.

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Titanium‐S23: A New Alloy with Ultra‐High Tensile Toughness Directly from the Solid‐State Processing of Recycled Ti–6Al–4V and Ti–5Al–5Mo–5V–3Cr Powders using Field Assisted Sintering Technology

Advanced Engineering Materials, EarlyView.
This study explores combining two existing aerospace titanium alloy powders, processing them via field‐assisted sintering technology and the subsequent discovery of a novel alloy composition, termed S23, with ultra‐high tensile toughness. Fine‐scale alpha precipitates favorably form in the alloy despite the relatively slow cooling, providing an ...

Measuring the tilt and slant of Chinese handwriting in primary school students: A computerized approach.

PLoS ONE, 2019
Background"Horizontal strokes should be level and vertical strokes should be straight" is a common guideline in the teaching of Chinese handwriting. Measuring deviations in level horizontal and straight vertical strokes in students' Chinese handwriting ...
