PROBLEM TO BE SOLVED: To correctly predict the material properties of a material by actually applying pre-working to a material to be worked with a press.;SOLUTION: These methods and this device include a first working stroke-working force relationship obtaining stage where the relationship of a working stroke and the working force to be obtained when applying a first press working to the material of the same kind as the material is calculated on the basis of the stress-strain relationship of the material and obtained, a second working stroke-working force relationship obtaining stage where the relationship of the working stroke and the working force where the relationship of the working stroke and the working force when actually applying the first press working to the material of the same kind as the material is measured and obtained and a stress-strain relationship predicting stage where the relationship of the stress and the strain of the material is predicted in the material of the same kind by using the relationship of the first working stroke and the working force and the second working stroke and the working force.;COPYRIGHT: (C)2009,JPO&INPIT
