Numerical modelling of crack propagation in ductile materials combining the GTN model and X-FEM
TL;DR: In this paper, a simulation of crack propagation in engineering materials whose failure results from void initiation, growth and coalescence is described via a Gurson type model accounting for the combined effects of strain hardening, thermal softening, viscoplasticity and void growth induced damage.

Respective/combined roles of thermal softening and dynamic recrystallization in adiabatic shear banding initiation
TL;DR: In this article, a physics-motivated model for strain hardening/softening describing the consequences of the competition operating between hardening (gliding) and softening due to dynamic recovery (DRC) and dynamic recrystallization (DRX) mechanisms is proposed.

Fracture analysis and constitutive modelling of ship structure steel behaviour regarding explosion
TL;DR: In this article, the identification of the microstructural damage mechanisms of a high purity (ferritic-pearlitic) mild steel employed as structural material in military ship building is discussed.

Modeling the Transition between Dense Metal and Damaged (Microporous) Metal Viscoplasticity
Patrice Longère,Patrice Longère,Anne-Gaëlle Geffroy,Anne-Gaëlle Geffroy,Bruno Leblé,André Dragon +5 more
TL;DR: In this article, a physically motivated approach was developed in order to describe the transition of behavior between dense metal plasticity and microporous metal polysilicon plasticity in three dimensions.

A constitutive model for a rate and temperature-dependent, plastically anisotropic titanium alloy
Miguel Ruiz de Sotto,Miguel Ruiz de Sotto,Patrice Longère,Véronique Doquet,Jessica Papasidero +4 more
TL;DR: In this paper, a constitutive model has been developed accounting for the combined effect of plastic orthotropy and tension/compression asymmetry, nonlinear isotropic and kinematic strain hardening, strain rate hardening and thermal softening.
