Abstract

A method is worked out for studying the process of self-healing of cracks in polymers. The criterion of self-healing of a crack — the degree of self-healing — is found, and its temperature dependence is determined. It is shown that a change of the relaxation spectrum of a polymer affects the process of self-healing occurring at the tip of a crack.
