Crystalline plasticity
WebDec 17, 2024 · As materials scientists and technologists working in the field of (poly) crystals plasticity, we all tend to provide valuable quantitative and qualitative indicators that describe the process→ (crystalline) … Crystal plasticity is a mesoscale computational technique that takes into account crystallographic anisotropy in modelling the mechanical behaviour of polycrystalline materials. The technique has typically been used to study deformation through the process of slip, however, there are some flavors of crystal plasticity that can incorporate other deformation mechanisms like twinning and phase transformations. Crystal plasticity is used to obtain the relationship between stress and st…
