To provide a method for simulating a die-casting with which the residual strain and the residual stress can accurately be analyzed.
The simulating method for die-casting is provided with the following steps, that is; a factor-making step S101 for dividing into fine factors as a die factor, a casting factor and pressurizing factor; a solidification analyzing step S301 for obtaining the temperature and a solid phase ratio in the casting factor based on a thermal characteristic value; a stress on the way analyzing step S302 for obtaining the strain, displacement and the stress in the casting factor based on pressurized force and mechanical characteristics by adding the pressurized force into the casting factor with the pressurizing factor; a cooling analyzing step S401 for obtaining the temperature of the casting factor based on the thermal characteristic value after making the whole casting factor to the solid phase; and a thermal stress analyzing step S402 for obtaining the strain, the displacement and the stress in the casting factor by using the strain, the displacement and the stress in the casting factor obtained in the stress on the way analyzing step S302 as the initial values.
