A biaxial sheet testing device was developed that prescribe arbitrary strain paths as a combination of plane strain tension and simple shear. In this way orthogonal strain paths changes with and without unloading can be obtained as well as cyclic shear loading with combined stretching. This relatively simple strain path yields interesting results in stress space when the stress crosses through the elastic domain.
