A New Model for Void Coalescence by Internal Necking [PDF]
, 2010 A micromechanical model for predicting the strain increment required to bring a damaged material element from the onset of void coalescence up to final fracture is developed based on simple kinematics arguments.

Tube Expansion by Single Point Incremental Forming: An Experimental and Numerical Investigation
Metals, 2021 In this paper, we revisit the formability of tube expansion by single point incremental forming to account for the material strain hardening and the non-proportional loading paths that were not taken into consideration in a previously published ...

Polymer‐Based Probabilistic Bits for Thermodynamic Computing
Advanced Physics Research, EarlyView.Electropolymerized conjugated polymers function as intrinsic entropy sources for probabilistic computing. Thermally driven conformational fluctuations of pendant triphenylamine groups produce stochastic resistance dynamics that are transduced into voltage‐gated probabilistic bits following logistic transfer functions identical to those of stochastic ...

Extension of a shear-controlled ductile fracture model considering the stress triaxiality and the Lode parameter [PDF]
, 2013 This paper is concerned with the extension of a shear-controlled ductile fracture criterion for accurate prediction of fracture forming limit diagrams (FFLD) in sheet metal forming processes. A shear-controlled ductile fracture criterion is extended to a

Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

A Plastic Damage Model with Stress Triaxiality-Dependent Hardening for Concrete [PDF]
, 2014 Emphases of this study were placed on the modelling of plastic damage behaviour of prestressed structural concrete, with special attention being paid to the stress-triaxiality dependent plastic hardening law and the corresponding damage evolution law.
