Abstract: The application discloses a time-dependent local stress-strain method for high-temperature structural strength and service life analysis. The method is aimed at a load component under high-temperature conditions, and the load component has a structural discontinuity area. The method includes: a step for obtaining working conditions, a step for obtaining material parameters, an elastoplasticity analysis step, a limit analysis step, an elasticity analysis step, a boundary condition setting step, an iterative operation step, and a result integration step. The application also discloses time-dependent local stress-strain tool software for high-temperature structural strength and service life analysis. The tool software includes: a parameter acquisition assembly, a finite element modeling and operation assembly, an iterative operation assembly, and a result display assembly.
