03-31-17 Numerical calculation of relaxation or creep

The parameters for the hyperelastic and time-dependent viscoelastic material model are determined by measurements of rubber samples. As second step the calculation by means of FEA is performed for the real component. Both, the time-dependent change of the restoring force for constant strain (relaxation) and the time-dependent change of the deflection for constant stress (creep), can be calculated.
