Abstract
With reference to two phase solids, Gurtin lias recently formulated a unified framework for Ginzburg-Landau's and Cahn-Hilliard's equations. The present paper deals with its possible extension to generalized continua described by arbitrary tensor-order parameters. The role of the configurational entropy is discussed in detail. Such an entropy allows to obtani kinetic rules even in the theoretical limit case of frictionless materials.
