|Abstract:||The determination of mechanical material parameters of elastomers is not easily possible. This is due to the fact that mechanical properties strongly depend on the composition of the underlying rubber compound and its manufacturing process. Furthermore, in uniaxial compression tests, data free of friction is required to gain realistic hyperelastic material parameters. However, low friction tests are normally difficult to achieve and cost-intensive. The alternative presented here is given by the deployment of suitable optimisation tools until the simulation results coincide with comparable low friction test results. This method proves to be much more time and cost efficient than rather elaborate low friction compression test setups eventually just yielding similar results.|
