Quasistatic evolution for a phase‐transition model: a Young measure approach

A quasistatic evolution problem for a phase transition model with nonconvex energy density is considered in terms of Young measures. We focus on the particular case of a finite number of phases. The new feature consists in the use of suitable regularity arguments in order to prove an existence result for a generalized notion of evolution (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
