Milling-creep age forming full-process simulation method considering residual stress field

The invention relates to a milling-creep age forming full-process simulation method considering a residual stress field, belongs to the technical field of sheet metal forming, and solves the problems that a simulation method in the prior art is low in simulation efficiency and inaccurate in result. According to the method, influences of initial and milling residual stress fields are considered in creep age forming simulation, and an initial residual stress test value and milling force are introduced into a graded milling simulation process to obtain residual stress simulation prediction values of a milled component surface and a full thickness range; according to the method, the residual stress grading simulation prediction value is obtained, the residual stress grading simulation prediction value is reconstructed, the overall residual stress reconstruction value is obtained, the overall residual stress reconstruction value is considered in creep age forming simulation, and therefore the simulation efficiency
