Finite Element Software for Rubber Products Design

Abstract

Automotive rubber products are subjected to large deformations during working conditions, they often contact with other parts and they show highly nonlinear material behavior. Using finite element software for complex analysis of rubber parts can be a good way, although it has to contain special modules. Different types of rubber materials require the curve fitting possibility and the wide range choice of the material models. It is also important to be able to describe the viscoelastic property and the hysteresis. The remeshing possibility can be a useful tool for large deformation and the working circumstances require the contact and self contact ability as well. This article compares some types of the finite element software available on the market based on the above mentioned features.

Fundamental Considerations for Finite Element Modelling of Rubber Material Tensile Test

“…To achieve better precise results and prediction in an assembly, by Finite Element Simulation (FES), model should be tested under the same force/loading conditions as the real-life assembly [6]. Uniaxial tests are well understandable and very easy to perform [7] but only uniaxial data is not enough to give us reliable coefficients of the model.…”
