摘要:
[Object] To provide a model setting method of a finite element model used for forming simulation, which is capable of executing forming simulation of a metal plate highly accurately and efficiently. [Solution] Provided is a model setting method for setting a finite element model for simulating forming of a metal plate by a forming tool by using a finite element method, by a processor included in a computer, the model setting method including: in setting a forming tool model that represents the forming tool, setting at least a part of a metal plate contacting surface that contacts the metal plate, in the forming tool model, as a surface layer that has characteristics of an elastic body or an elasto-plastic body; and setting a part that supports the surface layer in the forming tool model, as a base body that has characteristics of a rigid body.
