Two new in-plane torsion tests for the investigation of self-heating under pure shear cyclic loading

The fatigue limit under a pure shear loading is very complex to determine for thin sheet materials. In this paper, two new specimen geometries are proposed assess the condition using self-heating measurements isotropic material. Both disc-shaped with particular designs promote homogeneous stress field. Strain gauge confirmed that applied strain fields correspond condition. thermal were imaged by an infrared camera, demonstrating validity of 0D approach. way, limits could be determined.
