Deformation behaviour in advanced heat resistant materials during slow strain rate testing at elevated temperature

open access: yesTheoretical and Applied Mechanics Letters, 2014
In this study, slow strain rate tensile testing at elevated temperature is used to evaluate the influence of temperature and strain rate on deformation behaviour in two different austenitic alloys.

The Dynamic Energy Band Model of Contact‐Separation and Sliding Mode Triboelectric Charging of Polymers at the Metal‐Polymer Interface

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
Triboelectric charge generation at polymer‐metal interfaces arises from the interplay of polymer mechanochemistry, polymer physical properties, and material transfer, where ion‐derived dipoles modulate the interfacial potential and mechanochemically generated electronic states and work function differences drive electron transfer, providing a unified ...

A new micromechanism for transformation of small displacements to large rotations for a VOA

open access: yes, 2014
New movement translation micromechanism (MTM) is proposed to transfer and amplify small in-plane displacement or movement into large out-of-plane vertical displacement or rotation.

Micromechanism of Plastic Accumulation and Damage Initiation in Bearing Steels under Cyclic Shear Deformation: A Molecular Dynamics Study

open access: yes, 2022
Fatigue failure usually occurs on the subsurface in rolling bearings due to multiaxial and non-proportional fatigue loadings between rolling elements. One of the main stress components is the alternating shear stress.

Thermally Induced Creep and Viscoelastic Behavior of Copper Micropillar Arrays

open access: yesAdvanced Science, Volume 13, Issue 22, 17 April 2026.
Copper micropillar arrays are fabricated by electrodeposition within through‐glass‐via, and their thermally induced time‐dependent deformation is quantified. Nanoindentation creep, EBSD, and TEM reveal a heat‐treatment‐driven transition between grain‐boundary‐mediated deformation and dislocation‐dominated creep, while Kelvin modeling captures ...

Design and Modeling of a Bistable Spherical Compliant Micromechanism [PDF]

open access: yes, 2007
Compliant bistable mechanisms are mechanisms that have two stable equilibrium positions within their range of motion. Their bistability is mainly due to the elasticity of their members.

Tailoring Differentiated Multiscale Microstructure to Enhance the Mechanical Properties of Additively Manufactured AlCoFeNi2 at Room and High Temperatures via Annealing

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Additively manufactured AlCoFeNi series eutectic high‐entropy alloys (EHEAs) exhibit nonequilibrium dual‐phase microstructure in the as‐printed state, allowing them to be easily tailored through annealing to explore their strength–toughness potential.

A VIBRATION-ACTUATED BISTABLE MICROMECHANISM FOR MICROASSEMBLY

open access: yes, 2014
A novel method to switch an on-substrate bistable micromechanism is proposed. An external vibration is exploited to switch the micromechanism between its bistable positions. There is no need to build any actuators on substrate with this method.
