 The relevance is substantiated and the statement of the research problem for the plane stress state is formulated. The criterion structure is given in the form of a linear interpolation dependence, which connects two invariants of the stress tensor, which are responsible for ductile and brittle failure, respectively. The values of the limit invariants of the criterion limiting the interpolation range depend on the sign of the second principal stress. The basic experiment for determining the material constants includes standard long-term strength or, respectively, fatigue tests under uniaxial loading conditions and an identification experiment under biaxial loading conditions. The criteria were tested experimentally under the conditions of internal pressure with tension and tension with torsion.
