Abstract
In this study, material parameters of inelastic constitutive model are identified by using the steepest decent method (SDM) and random search (RS). For parameter identification the difference between the experimental results and the simulated data is minimized. Both of the two methods show good adaptability for cyclic plasticity experiment of pure titanium. A random number generator including multi-pseudo-random number generators is used in RS and the dependency of number of pseudo-random number generators is confirmed.
