Abstract: Based on the energy conservation law and mechanical properties of rock, the physical cellular automat (PCA), a new model set up by authors to simulate the nonlinear evolution of rock failure, is developed; and the PCA model can be used to simulate the macroscopic mechanical behaviors of rock system caused by the compositive results of the simple reciprocity among the partial cells in the rock. Entitative influence on the constitutive relation of rock is studied by way of PCA; and micro-mechanism of elasticity, brittleness and plasticity of rock is profoundly revealed. The ideas and conclusions of the paper can be used as an important reference to numerical simulation of meso-mechanics and design of new composite materials.

Key words: physical cellular automata, elasticity, brittleness and plasticity of rock, micro-and meso-mechanism
