The plastic deformation of polycrystalline metals is primarily carried by the crystallographic
glide of dislocations and growth of deformation twins. According to the thermodynamic …

A set of constitutive model parameters along with crystallography governs the activation of
deformation mechanisms in crystal plasticity. The constitutive parameters are typically …

In this work, we develop a multi-level constitutive model for polycrystalline metals that
deform by a combination of elasticity, slip and deformation twinning. It involves a two-level …

This paper advances crystallographically-based Olson-Cohen (direct γ→ α') and
deformation mechanism (indirect γ→ ε→ α') phase transformation models for predicting …

An orientation distribution is a necessary input in any crystal plasticity simulation. The
computational time involved in crystal plasticity simulations scales linearly with the number …

Insights from a detailed investigation into the anisotropic strain hardening,
tension/compression yield asymmetry, and evolution of crystallographic texture of rolled …

This work adapts a recently developed multi-level constitutive model for polycrystalline
metals that deform by a combination of elasticity, crystallographic slip, and deformation …

In this work, we develop a physically-based crystal plasticity model for the prediction of cyclic
tension–compression deformation of multi-phase materials, specifically dual-phase (DP) …

High strength low alloy (HSLA) steels are important metallic materials especially in the
defense and military sectors due to their superior mechanical properties and cost …

Deformation twinning is a subgrain mechanism that strongly influences the mechanical
response and microstructural evolution of metals especially those with low symmetry crystal …
