Evolving Phase Boundaries in Deformable Continua,
Abstract
Recently, Gurtin and Struthers 2 developed a dynamical theory of phase transitions in crystal-crystal systems in which the interface is sharp, coherent, and endowed with energy, entropy, and superficial force. A fundamental conceptual ingredient of the theory is the use of three force systems: deformational forces that act in response to the motion of material points; accretive forces that act within the crystal lattice to drive the crystallization process; attachment forces associated with the attachment and release of atoms as they are exchanged between phases. Here I will discuss the main results of the theory, which are constitutive equations and balance laws for the interface.
