Modelling dislocation glide over the initial part of a stress–strain curve metals received little attention up to now. However, is essential ones understanding fundamental relationship between inelastic deformation and evolution network structure. Therefore, we present model dislocation-driven under static loading conditions. We reproduce repeated cyclic uniaxial tensile tests on Interstitial-F...

Well-designed stretching-dominated lattices can form elastic metamaterials with high specific stiffness and strength. Their strongly anisotropic unstable nonlinear mechanical properties, however, limit their application to energy absorption. In contrast, bending-dominated are well known for absorption capacity stable response, but poor response. Here, we propose a new class of light-weight isot...

This article presents a 3-D multiplicative finite strain model for cold drawing (necking) in engineering thermoplastics. Amorphous as well as semi-crystalline polymers are considered. The notion of intermediate (local) stress-free configuration, that is associated with the multiplicative decomposition of the deformation gradient, is shown to provide an appropriate framework for the modeling and...
