A New Type of Cracks Adding to Griffith−Irwin Cracks

Аннотация

The distinctions in the description of the conditions of cracking of materials are revealed. For Griffith−Irwin cracks, fracture is determined by the magnitude of the stress-intensity factor at the crack tip; in the case of the new type of cracks, fracture occurs due to an increase in the stress concentrations up to singular concentrations.
