Scientific and Technical Section


The constitutive equations of plasticity theory for metastable materials with austenite-martensite transformations under proportional loading are proposed. The hardening and residual volume-change functions entering in the equations account for the influence of the stress deviator and the stress state rigidity. The structure of functions is specified with test results for 18–10 austenitic steels in the plane stress state at low temperatures as well as with x-ray data. The relations necessary for calculations are determined from the results of three basic tests. Calculated and experimental data are in good agreement.
