Conclusions 1. The breaks in the P-V diagrams are due to residual stresses in the specimen acquired at a certain stage of the technological process of its production or testing (welding stresses, stresses after plastic deformation, test temperature, etc.). 2. One of the chief causes of the appearance of breaks is an impermissibly harsh regime of fagituecrack formation. 3. To determine the true values of the crack resistance of a material (KIc), it is imperative that there be no breaks at all in the fracture diagram. Otherwise these values are exaggerated on account of the residual compressive stresses.
