Dislocation subgrain structures and modeling the plastic hardening of metallic single crystals [PDF]
A single crystal plasticity theory for insertion into finite element simulation is formulated using sequential laminates to model subgrain dislocation structures.

A multiscale crystal plasticity finite element model, which combines molecular dynamics with crystal plasticity theory, is proposed. In this model, the evolution equations for partial- and full-absorption dislocation loops are utilized.

Statistical approach to dislocation dynamics: From dislocation correlations to a multiple-slip continuum plasticity theory [PDF]
Due to recent successes of a statistical-based nonlocal continuum crystal plasticity theory for single-glide in explaining various aspects such as dislocation patterning and size-dependent plasticity, several attempts have been made to extend the theory ...

Investigation into the Effects of Prior Plasticity on Creep Accumulation in 316H Stainless Steel
Steel components in the boilers of nuclear reactors are subject to high temperatures and varying loading conditions. This can introduce time-dependent and time-independent plasticity, which can interact with one another.

The poor plasticity of metallic glasses (MGs) limits its applicability as engineering materials. Therefore, it is particularly important to find ways to improve the plasticity of metallic glasses.

Shock compression and spallation of single crystal tantalum [PDF]
We present molecular dynamics simulations of shock-induced plasticity and spall damage in single crystal Ta described by a recently developed embedded-atom-method (EAM) potential and a volumedependent qEAM potential.

Study of size effects in thin films by means of a crystal plasticity theory based on DiFT [PDF]
In a recent publication, we derived the mesoscale continuum theory of plasticity for multiple-slip systems of parallel edge dislocations, motivated by the statistical-based nonlocal continuum crystal plasticity theory for single-glide due to Yefimov et ...

A three-dimensional multiscale model of intergranular hydrogen-assisted cracking [PDF]
We present a three-dimensional model of intergranular hydrogen-embrittlement (HE) that accounts for: (i) the degradation of grain-boundary strength that arises from hydrogen coverage; (ii) grain-boundary diffusion of hydrogen; and (iii) a continuum model
