Input parameters estimation for nanoindentation model
Result description
Estimation of input parameters for the finite element nanoindentation model is discussed in this paper. The target of estimation is to find input parameters to achieve the best agreement between the numerical response of the model and the experiment. Forthat, a forward mode of the inverse analysis is applied. Three evolutionary algorithms are compared, particularly, single-objective genetic algorithm GRADE, multi-objective evolution strategy PAES and multi-objective genetic algorithm NSGA II are used.Objective functions are based on a difference between an experimental curve and a result from the model. Results of the method are presented on a set of illustrative problems created by computer-generated data and on an experimental curve.
