Abstract

The problem of dynamic loading of a material with a crack is investigated. Expressions for dynamic fracture toughness using the incubation-time criterion are obtained. It is shown that the graphs of dependence of dynamic fracture toughness on time to fracture qualitatively change with the crack length.
