Mechanics
Modeling of deformation and fracture of porous ceramic materials of various pore morphology under uniaxial tension was made by the movable cellular automaton method. It was shown that the samples with pores elongated across the loading direction has minimal strength. Besides, such samples were more sensitive to loading rate.
Using couple continual-discrete approach the tension of plastic material covered by porous brittle coating was modeled. The total porosity and pore morphology was varied. Computation results showed a tendency to quasi-periodic cracking of the coatings, while value of the total porosity and pore geometry has low influence on the distance between the cracks.
