Metal additive manufacturing (AM) has attracted much attention in recent years due to its
ability of producing parts with complex geometry. Unfortunately, the large temperature …

The bridge between classical continuum plasticity and crystal plasticity is becoming
narrower with continuously improved computational power and with engineers' desire to …

The collapse of pores plays an essential role in the shock initiation of high energy (HE)
materials. When these materials are subjected to shock loading, energy is localized in hot …

A coupled crystal plasticity phase field damage framework has been developed and applied
to modelling damage initiation. A novel implementation of a grain misorientation angle …

Selective laser melting is receiving increasing interest as an additive manufacturing
technique. Residual stresses induced by the large temperature gradients and …

In this study, a microdamage model by introducing the damage of crystal is proposed.
Damage variables are defined for each slip system, and the damage-coupled crystal …

A new finite strain thermomechanical model for the high-rate deformation of the β-polymorph
of cyclotetramethylene tetranitramine (β-HMX) has been developed and applied to …

A multiscale modeling strategy is used to quantify factors governing the temperature rise in
hot spots formed by pore collapse from supported and unsupported shock waves in the high …

We study the effect of the crystalline anisotropy and the relative importance of plasticity and
friction on the formation of hot-spots in polycrystalline and single crystal β-HMX when …

Molecular crystals are of importance in many applications including energetic materials and
pharmaceuticals. Here we focus on the energetic material cyclotetramethylene …
