Аннотация

3D computer simulation of mechanical behavior of a brittle porous material under uniaxial compression is considered. The movable cellular automaton method, which is a representative of particle methods in solid mechanics, is used for computation. In an initial structure the automata are positioned in fcc packing. The pores are set up explicitly by removing single automata from the initial structure. The computational results show that dependence of strength and elastic properties of the modeled material on porosity below percolation threshold (material with closed pores) differs from the dependence for porosity above the threshold (permeable material). The results obtained are in close agreement with available experimental data.
