Strain localization analysis using a multiscale model [PDF]
, 2007 In order to analyze the formability of steels in sheet metal forming, a ductility loss criterion is coupled with a multiscale model. The behavior at the mesoscopic (grain) scale is modeled by a large strain micromechanical constitutive law, which is then

Characterization of Material Viscoelasticity at Large Deformations
Applied Rheology, 2014 Mechanical properties of various technological materials at large deformations are proposed to characterize by means of some generalized parameters obtained at large oscillation strains but not related to any definite rheological equations.

One-dimensional electroosmosis consolidation model considering variable saturation
Yantu gongcheng xuebao, 2017 The existing models for electroosmosis are based on the hypothesis of fully saturated soil regime. Variable saturation occurs in the soil regime, thus a new model is expected to improve the calculation accuracy.

Separately global solutions to rate-independent processes in large-strain inelasticity
, 2021 In this paper, we introduce the notion of separately global solutions for large-strain rate-independent systems, and we provide an existence result for a model describing bulk damage.

Pseudoelasticity at Large Strains in Au Nanocrystals [PDF]
Physical Review Letters, 2018 Pseudoelasticity in metals is typically associated with phase transformations (e.g., shape memory alloys) but has recently been observed in sub-10 nm Ag nanocrystals that rapidly recovered their original shape after deformation to large strains. The discovery of pseudoelasticity in nanoscale metals dramatically changes the current understanding of the ...

Simulations of thermal softening in large strain thermoplasticity
Engineering Transactions, 2016 This paper deals with numerical simulations of the thermoplastic behaviour of isotropic materials undergoing large deformations. The attention is focused on the constitutive modelling of thermal softening understood here as a reduction of the plastic ...
