Abstract
The stress-strain state of a rectangular plate with a central circular hole and a disk with an edge notch is examined in both the elastic and elastoplastic statement. The stress intensity factors at the tips of cracks emerging from the hole and notch are determined. Parameters describing the process of crack initiation and development are established in the zone of the stress risers. The results of calculations are compared with experimental data in evaluating the period of macrocrack initiation.
