Abstract
In this paper genetic algorithm and sensitivity analysis are used to identify 6
parameters of Chaboche kinematic hardening model using repeated Finite element (FE)
simulations of indentation test. Five of them are material constants of Chaboche kinematic
hardening model itself. The last one represents the stiffness of the foundation and the
indenter. To obtain experimental data indentation test under cyclic loading on universal
tensile testing machine was performed. Because for sensitivity analysis to obtain all possible
combinations of parameters and its values large number of simulation have to be performed
supercomputer Anselm hosted by IT4Innovation has been used. Advantage of using
supercomputer is that every simulation could use multiple cores which will reduce
computational time. Moreover, since each simulation is independent, computational time
could be further reduced by performing multiple simulations at the same time. It is clear from
the comparison of both methods that the genetic algorithm is very good choice for the
parameter estimation.
