Accurate crystal plasticity models that faithfully capture the behavior of single crystals under
a wide range of loading conditions, such as loading direction, strain rate, and temperature …

In this work, we extend a dislocation-density based constitutive theory for the dynamic
thermomechanical behavior of crystals to body centered cubic (BCC) tantalum. Strain rate …

Tungsten is considered as the plasma-facing material in the nuclear fusion device, which
has to withstand coupled irradiation, mechanical and thermal conditions. To guarantee the …

It is generally recognized that single crystals exhibit orientation-dependent elastic and
plastic responses. However, it is less known how the dynamic tensile, or spall, strength …

Microcracking is a prevalent and critical issue in additively manufactured tungsten,
significantly restricting its safety-critical engineering applications. Till now, most of our …

A physically-informed continuum crystal plasticity model is presented to elucidate
deformation mechanisms, dislocation evolution and the non-Schmid effect in body-centered …

The Ti 37 V 15 Nb 22 Hf 23 W 3 is a multi-principal refractory alloy with exceptional strength
and ductility at room temperature. For potential high-temperature applications, it is of great …

This work presents an open source, dislocation density based crystal plasticity modeling
framework, ρ-CP. A Kocks-type thermally activated flow is used for accounting for the …

High-pressure torsion was applied to join two disks of single-phase equiatomic fcc
CoCrFeMnNi and bcc HfNbTaTiZr high entropy alloys (HEAs). After 15 revolutions a bulk …

Understanding the effect of grain boundaries (GBs) on the deformation and spall behavior is
critical to designing materials with tailored failure responses under dynamic loading. This …
