The Equivalent Stresses at Calculation of Creep Rupture of Metals Under Complex Stress State (Review)

The criteria of creep rupture of metals under complex stress state are based on conception of equivalent stress σe. The basic attention is gived to determination of dependence of equivalent stress from the main stresses σ1, σ2, σ3 and to determination of dependence of rupture time from value σe. The detailed review of dependencies σe(σ1, σ2, σ3) is described, which were proposed by domestic and foreign scientists. The equivalent stresses σe, which are depended only on main stresses, and σe, which are depended also on the additional constants, are considered separately.
