Abstract

Concepts regarding the mechanisms of defect formation in material structures are examined. Problems of the kinetic theory of strength and the impact of thermal fluctuations on the initiation of microcracks and the accumulation of irreversible damage in materials are analyzed. An approach to constructing mathematical models of the damage accumulation kinetics using hypothetical schemes of quasi-chemical reaction is proposed.
