Abstract
This study focuses on identifying the parameters of a nonlinear viscoelastic model from Berkovich nanoindentation experiment of an epoxy polymer using finite element-based inverse analysis approach. Instead of traditional approach of online optimization of model parameters, where finite element computation is placed inside of the optimization algorithm, this study utilizes a surrogate or meta-modeling approach. The surrogate model, which is based on Proper Orthogonal Decomposition (POD) and Radial Basis Function (RBF), is trained with finite element load–displacement data obtained by varying the different model parameters in a parameter space. Once trained POD–RBF based surrogate model is used to approximate the nanoindentation simulation data inside a multi-objective Genetic Algorithm. Current efforts are focused to validate identified parameter set of nonlinear viscoelastic model for different experimental conditions (e.g. maximum load, loading/unloading rate).
