Abstract
Semi-brittle polycrystalline ceramic materials (e.g. MgO) have a nonlinear and complex overall response to applied loads due to development of limited plasticity and internal microdefects, e.g. [1]. All microdefects act as stress concentrators and locally change the state of stress, leading to the development of mesocracks and finally macrocracks. Experimental results show that defects develop mainly intergranularly and cause inhomogeneity and induced anisotropy of the solid. Modelling of such material response is possible by application of effective continuum models (e.g. [2–7]) or phenomenological ones introducing of internal state variable (e.g. [8–11])
