SELECTION METHOD OF COSTITUTIVE EQUATIONS

摘要

The present invention is to provide the constitutive equation suggesting method of selection with a simple equation of the best configuration information for metal material thus. The present invention of achievement for above-mentioned target, in a kind of selection of the configuration equation selection method for constitutive equation, its mechanical performance that metal alloy is represented by device uses the data of the multiple materials emphasized and the pressure of the tensile test testing data acquisition step by obtaining a storage equipment; Parameter material calculation uses the data of the acquisition with actual stress and pressure, and the configuration parameters of equation are calculated and stored by terminal; Raw material information and title by device storage material; A mistake and material ultimate strength corresponding with input are extracted by the error for the intensity of terminal allowed; It is it is characterized in that it includes a; It is determining and is exporting in the phase error equation configuration to terminal, representing the configuration extraction of the equation of lowest error.
