In this study, we proposed a method, which is a combination of qualitative analysis and
quantitative analysis, to establish dislocation-based plasticity model, and assessed the time …

The dynamic response of crystalline materials subjected to extreme shock compression is
not well understood. The interaction between the propagating shock wave and the material's …

There are many theoretical and computational investigations devoted to the dislocation
mechanism based crystal plasticity under static or quasi-static conditions. However, the …

A mechanistic model of shock-wave-induced viscoplasticity is parameterized for three
polycrystalline metals: Cu, Ni, and Al. The model is also extended to higher stress wave …

This article examines the role that the choice of a dislocation mobility law has in the study of
plastic relaxation at shock fronts. Five different mobility laws, two of them phenomenological …

Multiscale dislocation dynamics plasticity (MDDP) was used to investigate shock-induced
deformation in monocrystalline copper. In order to enhance the numerical simulations, a …

Unraveling the deformation mechanism of materials under extremely high strain rate is
critical from both scientific and engineering viewpoints. The elastodynamic effect of 3D high …

In strain-gradient plasticity, the length scale controlling size effect has been attributed to so-
called geometrically necessary dislocations. This size dependency in plasticity can also be …

Homogeneous nucleation of dislocations is the dominant dislocation generation mechanism
at strain rates above 108 s− 1; at those rates, homogeneous nucleation dominates the …

In this article, it is demonstrated that current methods of modelling plasticity as the collective
motion of discrete dislocations, such as two-dimensional discrete dislocation plasticity …
