PREDICTION OF LIFE OF 12X18H10T STEEL IN ISOTHERMAL CREEP IN UNIAXIAL TENSION

Doyar I. A., Poshivalov V. P.

      The paper deals with a method of prediction of the structural material life in isothermal creep in uniaxial stationary loading, based on a strained failure criterion, which suggests that a limited state of material is measured by a critical value of the stored creep strain. The determining creep equations are stochastically linearized. It allowed an analytical determination of the basic distribution characteristics of creep strain and construction of a stochastic failure model of the 12X18HX10 corrosion-resistant steel.
