»Microstructures in Shape Memory Alloys: Rigidity vs Flexibility «

Abstract:
Shape-memory materials undergo a first order, diffusionless phase transformation, in which symmetry is lost. Mathematically, they are often modelled by non-convex, multi-well energies within the framework of the calculus of variations. Minimizers of these energies are often subject to a fascinating dichotomy: While solutions with high regularity are often quite rigid, solutions with low regularity are in many cases very flexible. I will discuss this in the context of the cubic-to-orthorhombic phase transformation, where this dichotomy already arises for the geometrically linearized theory of elasticity. Further, I will present first results which quantify this dichotomy. This is based on joint work with C. Zillinger and B. Zwicknagl.
