Incompatible 4-node element for gradient-dependent plasticity
, 2004 In gradient-dependent plasticity theory, the yield strength depends on the Laplacian of an equivalent plastic strain measure (hardening parameter), and the consistency condition results in a differential equation with respect to the plastic multiplier ...

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

A gradient plasticity model for the simulation of shear localization
Advances in Mechanical Engineering, 2017 The numerical simulation of shear localization under high strain rates can be modeled by a system of four partial differential equations including conservation of momentum, conservation of energy, elastic, and inelastic constitutive relations.

A new hardening law for strain gradient plasticity
, 2000 A new hardening law of the strain gradient theory is proposed in this paper, which retains the essential structure of the incremental version of conventional J(2) deformation theory and obeys thermodynamic restrictions.

Strain gradient plasticity analysis of elasto-plastic contact between rough surfaces [PDF]
, 2016 From a microscopic point of view, the real contact area between two rough surfaces is the sum of the areas of contact between facing asperities. Since the real contact area is a fraction of the nominal contact area, the real contact pressure is much ...

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

On the non-quadratic defect energy in strain gradient crystal plasticity [PDF]
, 2019 Strain gradient crystal plasticity (SGCP) represents a very promising way to account for size effects in miniaturized components, thanks to the intrinsic length scale(s) embedded.

Advanced Engineering Materials, EarlyView.This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.
