The development of deformation and fracture under uniaxial loading conditions in porous ceramic materials with the pore space having regular and stochastic structures of various types has been studied by method of movable cellular automata. The influence of the porous structure on the dynamics of damage nucleation and development is been analyzed, and a correlation between the effective stiffness of porous samples and the rate of damage accumulation is found. It is concluded that brittle materials can exhibit quasi-viscous fracture determined entirely by the pore space structure.
