Résumé

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