摘要
To provide a material property data calculation method which can obtain a proper analysis result even when performing a spot weld simulation the junction objects of which are materials of different materials.SOLUTION: A method for calculating material property data when simulating a numerical value analysis simulation where a consistent process of heating, melting, cooling is simulated includes a liquid phase calculation processing of calculating a maximum liquid phase ratio from a temperature, a solidus line, a liquidus line of a material in the heating and melting process, a melt mixture ratio calculation processing of calculating a molten nugget volume for each material from the maximum liquidus ratio to obtain a melt mixture ratio, and a molten nugget material property data calculation processing of calculating material property data of a molten nugget used in the cooling process from the molten mixture ratio and from material property data for each material.SELECTED DRAWING: Figure 2
