Abstract
The method of calculating the limiting state of solids built on known elasticity relations is proposed to describe stable and unstable deformation of the defect-containing material. The basis for the method is evaluating the rigidity distribution over the body volume. The limiting state of the body is associated with the total negative rigidity of the body and loading system. An increase in damaged area sizes that are much smaller than component sizes is shown to result in stability and carrying capacity losses of the whole component at a certain rigidity of this area. Rigidity calculations for the bodies in the form of a sphere, cylinder or plate with inclusions as well as a crack-containing plate are cited.
