The equivalent stresses at calculation of creep rupture of metals under complex stress state (review)
A. M. Lokoshchenko Research Institute of Mechanics, M. V. Lomonosov Moscow State University
Abstract:
The criteria of creep rupture of metals under complex stress state are based on conception of equivalent stress $\sigma_e$. The basic attention is gived to determination of dependence of equivalent stress from the
main stresses $\sigma_1,\sigma_2,\sigma_3$ and to determination of dependence of rupture time from value $\sigma_e$.
The detailed review of dependencies $\sigma_e(\sigma_1,\sigma_2,\sigma_3)$ is described, which were proposed by domestic and foreign scientists. The equivalent stresses $\sigma_e$, which are depended only on main stresses, and $\sigma_e$, which are depended also on the additional constants, are considered separately. By using of statistical methods the formulas for $\sigma_e$ are obtained for various kinds of complex stress states.
Key words:
creep rupture, metals, complex stress state, criteria, equivalent stresses, review, statistical methods.
