Research Interest
Primary research interest is in experimental and numerical studies in emerging materials (nanocrystalline metals and polymers), and new metal alloys, related to the constitutive modeling of finite plastic behavior at high strain rates and quasi‑static loading; and damage & failure modeling of composite materials and ceramics. Secondary research interests are in development of yield and fracture criteria for granular rock materials and ceramics, elastic‑plastic fracture mechanics (especially fatigue crack propagation in metallic solids), metal forming, and in elastic‑plastic constitutive models for granular rock materials and ceramics.
