Deformation and Strength of Malleable Cast Iron in the Complex Stressed State

We analyze the experimental data on the specific features of deformation, damageability, and strength of malleable cast iron obtained in testing tubular specimens under conditions of simple loading by axial forces and internal pressure. It is shown that the degradation of the structure of the material depends on the parameters of the stressed state. New criteria required for the description of the limiting states of yield and fracture are established.
