Abstract: The critical load (force) is estimated for a space with a disk-shaped crack, in the case when a concentrated force acts on its edges along the circumference. It is shown that it is impossible to determine the ultimate force with the help of classical fracture criteria, so a structural strength criterion formulated for axisymmetric problems is used. The relationship between fracture toughness and crack size is investigated and a two-criteria fracture diagram is constructed.
Keywords: disc-shaped crack, critical force, structural criterion, fracture toughness, short cracks.
