The purpose of the work was to calculate experimentally the study of crack resistance when mixing deformation modes and to study the effect of the previous thermomechanical load on the characteristics of crack resistance. A methodology has been developed for predicting the crack resistance on the lower shelf of the temperature dependence of fracture toughness, which predicts an increase in the result of a preliminary thermomechanical load of crack resistance in proportion to the increase in the load of the normal separation component.
