Determination of Johnson-Cook material model parameters by an optimization approach using the fireworks algorithm

The accurate description of materials behavior is essential when investigating the application of these materials in the industrial practice. For this purpose, experimental data are fitted to suitable constitutive laws using various methods. In this paper, the determination of Johnson Cook material model parameters for AISI 316L stainless steel is performed using an optimization approach. More specifically, the Fireworks algorithm is employed to determine the appropriate material parameters for AISI 316L steel. The results indicate a sufficient performance of the optimization approach, which can be further developed and applied for other types of materials as well.
