Multiscale Ductile Damage in Metals & Alloys

Ductile damage in metals is the main focus of the research. My research group is involved in understanding and developing multiscale computational frameworks for materials undergoing ductile deformation and failure. We have investigated single and dual phase alloys in this context and developed computational frameworks to simulate ductile damage at various length scales.
