ABSTRACT:
A method of evaluating contact characteristics of an object having a roughness includes setting geometric shape data for the roughness; creating a roughness model and a structure model that comes in contact with the roughness, based on the geometric shape data set; making the roughness model and the structure model come in contact with each other; acquiring a physical amount occurring at least one of a contact region of the roughness model and a contact region of the structure model; and obtaining an evaluation value for evaluating a real contact state in the contact region between the roughness model and the structure model, from the physical amount acquired.
