Abstract:
It is proposed to construct long-term strength and creep relations for metals on the basis of the Coulomb–Mohr criterion. The creep equations and the long-term strength criterion for plane stress are analyzed in detail. Results of long-term strength calculations are compared with data of experiments with metallic materials. It is established that theoretical and experimental results are in satisfactory agreement.
Keywords:
plasticity, creep, long-term strength of metals, Coulomb–Mohr yield criterion.
