More Information
Summary:The method involves providing the characteristic features of flat semi-finished material to determine deformation parameter, in a computer database. The equivalent plastic strain on preset load path is determined using content in database or determined deformation parameter, based on the triaxiality or similar to the voltage characterizing suitable size. A three-dimensional space is formed with the coordinate axes based on the change in thickness of the flat semi-finished material. The surface of semi-finished material is generated in the three dimensional space. Independent claims are included for the following: (1) computer system; and (2) machine readable medium storing program for determining instability conditions of flat semi-finished material.
