ABSTRACT
Constitutive models in combination with finite element implementations are required for the prediction of the mechanical behaviour of rubberlike solids within vehicle components, which then provide a basis for simulations in multi-body systems. This chapter describes the experimental investigation of the amplitude and frequency-dependent mechanical properties in rubberlike solids at constant temperature. Quasi-static uniaxial, equibiaxial and simple shear tests on natural rubber compounds were carried out in order to analyze their mechanical responses including the typical stress softening effect. The parameters of the hyperelastic model may be determined on the basis of the quasi-static tests. Quasi-static stress strain curves were recorded at four constant temperatures for uniaxial compression-tension and simple shear. In addition, cyclic uniaxial tension tests were performed for the determination of dynamical properties. The chapter summarizes a constitutive model which captures the typical mechanical phenomena observed during the experiment investigation.
