Subject: Variational Principle for Probabilistic Measure in Theory of Materials with Random Microstructures and Beyond

Materials with random microstructures can be adequately described only in probabilistic terms. One of the problems that arise is: how to find probabilistic characteristics of local fields (stresses, currents, etc.), if probability distributions of material characteristics are known? This is one of the two topics of the talk. The second topic is closely related to the first one and concerned thermodynamics of microstructure evolution. It will be argued that classical thermodynamics is not sufficient for macroscopic description of solids, and there is one more law of thermodynamics which controls evolution of microstructures.
