3D modeling of fracture of brittle porous materials using movable cellular automaton method

Reporter: Roman N.V.

3D computer simulation of mechanical behavior of a brittle porous material under uniaxial compression is considered. 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 the curve of porosity dependence of strength and elastic properties of the modeled specimens has a break at the porosity about 20%, i.e. percolation threshold. The obtained results are in a good agreement with the available experimental data.
