Abstract
A model of dynamical process and stochastic jump has been put forward to study the pattern evolution in damage-fracture. According to the fi nal states of evolution processes, the evolution modes can be classifi ed as globally stable modes (GS modes) arid evolution induced catastro phic modes (ElC modes); the latter are responsible for fracture. A sta tistical description is introduced to clarify the pattern evolution in this paper. It is indicated that the appearance of fracture in disord ered materials should be depicted by probability distribution function .
