摘要

Simulation method of the present invention calculates the plastic strain from the stress data and strain data, and calculates the plastic strain rate from time change of the plastic strain. Set the viscosity function of the plastic strain rate as a parameter, to set the isotropic hardening model for plastic strain as a parameter. Also, the simulation method of the present invention is to introduce a viscous functions and isotropic hardening model in the yield stress of the mechanical structure of formula Chaboche model is determined by a global non-linear numerical optimization method the material constant of the mechanical configuration type. Furthermore, the simulation method of the present invention, by using the determined mechanical structure formula to calculate the stress and strain.
