A new failure criterion for materials with different strength in tension and compression is proposed. Experiments with tube specimens made from different types of cast iron with tensile strength 100, 150 and 200 MPa and biaxial stress state -^=co, 1, 0.5, 0, -2, -oo and pure forstonwere carried out. The proposed criterion is in good agreement with the experimental data and can be successfully used in design. The accuracy of other failure criteria is discussed, too.
