Моделирование деформационного поведения пористой керамики

Finite-element simulation results are used to analyze the deformation behavior of porous ceramics. Localization regions are shown to form in the material under loading. They are at an angle of 45° to the loading axis and divide the material into fragments, whose average size equals the average distance between pores. Three stages can be distinguished in the loading process of such a material: a stage, at which a loaded material experiences no local fracture, a stage of nonlinear accumulation of a fractured volume and a linear stage up to total fracture.
