Damage and fracture: Crystal plasticity models

Resumo

This paper completes the review of recent (last 15 years) publications on experimental and theoretical methods and approaches for studying damage accumulation and fracture in crystalline solids. It summarizes the works that describe damage and fracture using an approach based on crystal plasticity. These works study the propagation of trans- and intergranular cracks, microvoid nucleation and evolution in two-phase steel specimens, crack growth in low- and high-cycle fatigue, and analyze the deformation behavior of various materials under high radiation that strongly affects mechanical properties. Much attention is given to the papers on the numerical implementation of crystal plasticity models, particularly, modifications of finite element models used in application packages for damage and fracture description.
