Abstract
A phenomenological theory of fracture is developed to establish formal rules for the detection of flaws in materials at different stages of production, determine the extent of degradation of their properties du ring service and the potential for restoring them to their original va lues, and predict the residual life of machine parts and structural el ements. The model is based on the concept of the gradual accumulation of microscopic damages under the influence of applied loads. This proc ess is interrupted at a certain moment of time by macroscopic fracture .
