Abstract: This conference contribution focusses on the invertibility of non-ideal material tests to accurately determine material parameters. This is done by attempting to model non-ideal test cases and comparing strains as well as force history to the experimental data. An inverse analysis is performed that determines material properties and boundary conditions simultaneously. This idea is investigated using virtual experimental data. The virtual experimental data is obtained by performing a finite element analysis with known material parameters and boundary conditions. The inverse analysis then aims to recover the known material and boundary conditions without using any prior knowledge of the true parameters. This is done to see if such a problem is in fact invertible and if the material and test parameters can be estimated simultaneously.
