To understand the underlying strengthening mechanisms, thermal activation processes are
investigated from stress-strain measurements with varying temperatures and strain rates for …

We use a physically-based crystal plasticity model to predict the yield strength of body-
centered cubic (bcc) tungsten single crystals subjected to uniaxial loading. Our model …

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 …

Проблема построения конститутивных моделей, позволяющих описывать поведение
материалов в широких диапазонах изменения параметров воздействия (температур …

Tungsten plays a significant role in the nuclear industry, in which defects are generated
upon exposure to irradiation. Irradiation-induced defects, such as dislocation loops and …

Crystal plasticity-finite element method (CP-FEM) is now widely used to understand the
mechanical response of polycrystalline materials. However, quantitative mesh convergence …

To elucidate the relationship between microstructural characteristics and mechanical
properties in additively manufactured (AM) maraging steel, this study introduces a …

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 …

Nickel (Ni)-based superalloys are used for safety-critical components in the aerospace
industry because of their high strength at elevated temperatures. These materials are …

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 …
