Advancement of high-temperature structural design method for fast reactor components. Part II: Inelastic constitutive model for 316FR
Accurate estimation of strain and stress is essential in the design of various components operated at severe loading conditions. Because inelastic deformation can not be avoided in high-temperature components of fast breeder reactor plants and its accurate estimation is crucial to ensure the long-term integrity of the plant. An inelastic constitutive model for description of cyclic deformation behavior of 316FR under wide range of temperature was developed in this study. The kinematic hardening rule proposed by Ohno and Wang was employed as a basis and temperature-dependent deformation behavior under monotonic and cyclic loading conditions was introduced. It was demonstrated through extensive comparisons of the simulations with test results, that the developed constitutive model can simulate deformation behavior under various conditions including temperature change with a sufficient accuracy for structural integrity assessment of fast breeder reactor components.
