The article presents the theoretical and computational analysis of the fatigue tested specimens loaded by bending and torsion. The testing device allows loading by constant turn of the clamping parts. The stress and strain magnitude in test depends on the material characteristics and shape of the specimen. The calculations will be realized by finite element method (FEM). The results will be verified with the experimental measurement applying the optical system ARAMIS.
