Numerical investigation of the temperature dependence of dynamic yield stress of typical BCC metals under shock loading with a dislocation-based constitutive model
TL;DR: In this article, a dislocation-based constitutive model was proposed to investigate the temperature dependence of the dynamic yield stress of BCC metals under extreme conditions, in which the dislocation generation equation was proposed from the viewpoint of dissipation energy.

A dislocation-based explanation of quasi-elastic release in shock-loaded aluminum
TL;DR: In this article, a dislocation-based model, taking into account dislocation substructures and evolution, is applied to simulate the elastic-plastic response of both single-crystal and polycrystalline aluminum.

Scale dependence of thermal hardening of fcc metals under shock loading
TL;DR: In this article, a dislocation-based constitutive model is applied to revisit the anomalous thermal hardening behavior of fcc metals under shock loading, and two scale-dependent dislocation motion mechanisms are found to dominate the thermal hardness.

Revisiting the Power Law Characteristics of the Plastic Shock Front under Shock Loading.
TL;DR: In this paper, a simple dislocation-based continuum model was developed, which reproduced the third power law and revealed very good agreement with recent experiments of multiple types of metals quantitatively.

Assessment of the time-dependent behavior of dislocation multiplication under shock loading
TL;DR: Wang et al. as mentioned in this paper proposed a method, which is a combination of qualitative analysis and quantitative analysis, to establish dislocation-based plasticity model, and assessed the time-dependent behavior of dislocation multiplication under shock loading.
