Abstract
The variant of a continuum model describing joint deformation and accumulation of microdamages in elastic-brittle materials is presented. The microdamageability is considered as the process of origin of a system of flat elliptic or circular microcracks randomly dispersed over volume, the concentration of which increases with a load. The damageable material is simulated by the continuous medium, for which the elastic symmetry and non-linear law of deformation are attributed to the pattern of the microstrength distribution, microfracture mechanism, and the mode of the stress state induced in the body. The model provided is used to describe the possible mechanism of non-linear deformation for practically all materials within the range of small strains.
