THE STOCHASTIC FORMULATION OF MICROCRACKS EVOLUTION
微裂纹演化的随机模型

The general problem in various fracture processes microcracks or voids evolution has been investigated by employing non-equilibrium statistical concept and method. The kinetic equation of microcrack evolution is derived from multivariated master equation describing the process of microcracks evolution. The way how to connect micro mechanism with macro process is indicated. And the inherent properties of distrubution function of microcracks is discussed.
