Abstract

Abstract The properties of uncured rubber are characterized by a viscoelastic material formulation in order to develop a finite element method (FEM) to predict the deformation behavior of this material during processing. As material formulation, a viscoelastic material model is considered, which consists of a nonlinear Hooke spring connected in parallel to a finite number of Maxwell elements. To identify the material parameters, various tests have to be conducted. The chosen test procedure and data analysis strategy are presented. An evolutionary optimization procedure is used to fit the material parameters to the measurements by minimizing the mean square error of the approximation. At the end, the suitability of the chosen material model and the identified material parameters is shown. Finally, the result of a molding test is compared to the corresponding FEM simulation.
