Modelling evolution of anisotropy in metals using crystal plasticity [PDF]

open access: yes, 2013
Many metals used in modern engineering exhibit anisotropy. A common assumption when modelling anisotropic metals is that the level of anisotropy is fixed throughout the calculation. As it is well understood that processes such as cold rolling, forging

Review of new methods of modelling plasticity [PDF]

open access: yes, 2013
Recent short pulse (femtosecond) laser experiments have shown the existence of a so called superelastic precursor for short time periods after shock wave formation.

Multiscale crystal plasticity finite element model for investigating the irradiation hardening and defect evolution mechanism of A508-3 steel

open access: yesNuclear Materials and Energy, 2022
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.

Diffuse-interface polycrystal plasticity: expressing grain boundaries as geometrically necessary dislocations

open access: yesMaterials Theory, 2017
The standard way of modeling plasticity in polycrystals is by using the crystal plasticity model for single crystals in each grain, and imposing suitable traction and slip boundary conditions across grain boundaries.
