| Zusammenfassung | Certain memory effects, that show up during the deformation of many materials of technical importance, can be described by a law of linear viscoelasticity. Using inner variables, arbitrary signals in time can be handled easily. In the special case of harmonic signals, this naturally leads to frequency dependend complex moduli. The identification of the associated parameters can be performed by a process of optimisation using iterative simulation of the experiment and the comparison of the calculation with the experimental data. Several experiments with one material can be combined to yield a united set of parameters. Results of this process will be presented. |
