Hillert Materials Modeling Colloquium series XIX: Critical stress determination in metallic materials

Professor Huseyin Sehitoglu is the editor of the Shape Memory and Superelasticity journal. In this presentation he discusses new theoretical developments in areas like interfaces in martensites, the evolution of slip in shape memory alloys and the determination of Critical Resolved Shear Stress (CRSS). He also talks about the application of these theories.
