摘要:The effects of stochastic extension on the statistical evolution of the ideal microcracksystem are discussed. First. a general theoretical formulation and an expression for thetransition probability of extension process are presented, then the features of evolution instochastic model are demonstrated by several numerical results and compared with that indeterministic model.
