Material parametrization of natural rubber based compound and characterization of crack propagation under consideration of dissipative effects

Abstract Most concepts to characterize crack propagation were developed for elastic materials. When applying these methods elastomers, the question is how inherent energy dissipation of material affects cracking behavior. This contribution presents a numerical analysis growth in natural rubber taking due visco-elastic behavior into account. For this purpose, experimental tests first carried out under different load conditions parameterize Prony series as well Bergström–Boyce model with results. The parameterized was then used perform investigations respect Using FE-software system ANSYS and concept forces, influence proportion dissipative components discussed.
