In this research, the material constants of Gurson model for porous elastic-plastic materials are identified. Measurement data, obtained by simple experiments (compressive test and tensile test) with carbon steel (S25C) specimen, are used. The identification method is based on an inverse analysis using Bayes Formula and the finite element method. Preliminarily, sensitivity analyses are performed for verification of parameter-independency, and efficient identification procedure is proposed.
