Nucleation and Growth in Elastodynamics
Lev Truskinovsky · Kluwer Academic Publishers eBooks · 2006
Solids undergoing martensitic phase transformations are currently a subject of intense interest in mechanics. In spite of recent progress in understanding the absolute stability of elastic phases under applied loads, the presence of metastable configurations remains a major puzzle. In this overview we presented the simplest possible discussion of nucleation and growth phenomena in the framework of the dynamical theory of elastic rods. We argue that the resolution of an apparent nonuniqueness at the continuum level requires “de-homogenization” of the main system of equations and the detailed description of the processes at micro scale.
