Slip in face centred cubic (fcc) metals is well documented to occur on {111} planes in< 110>
directions. In body centred cubic (bcc) metals, the slip direction is also well established to …

Dislocations play a vital role in the mechanical behavior of crystalline materials during
deformation. To capture dislocation phenomena across all relevant scales, a multiscale …

A novel dislocation-density-based crystal plasticity model for nanocrystalline face-centered
cubic metals is developed based on the thermally-activated mechanism of dislocations …

Featured with various excellent mechanical properties, the high strength Al-Zn-Mg-Cu alloys
(7xxx series) have become one of the most widely-used metal materials. During the hot …

Abstract In 1969, Rice and Tracey proposed that the rate of void growth during ductile failure
is a strong function of the hydrostatic stress state. Numerous in-situ x-ray computed …

The high thermal gradients during the laser powder bed fusion (LPBF) process induce an
inhomogeneous microstructure with anisotropic mechanical properties. This study …

A three-dimensional computational framework has been developed combining a crystal
plasticity (CP) and a phase-field (PF) approach that can efficiently simulate static …

An internal-state-variable based self-consistent constitutive model was proposed for unified
prediction of flow stress and microstructure evolution during hot working of wrought two …

Film cooling hole structures significantly influence the mechanical behavior of a single
crystal turbine blade. This study investigates the tensile behavior of nickel-based single …

In this work, the grain-scale elastoplastic deformation behavior of coarse-grained body
centered cubic (BCC) tantalum was simulated using a crystal plasticity finite element method …
