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 are realized by finite element method (FEM). The obtained results are verified with the experimental measurement applying the optical system ARAMIS.

In order to profound the function of stress wave in vibration turning and present the effectiveness of instant change of stress and strain in the workpiece under the shock load,put forward a simulation model of materials obeying Prandtl-Reuss flow principle with non-linear constitutive relation for vibration turning with low frequency.Related techniques have been stressed on criterion of chip separation from the workpiece, friction between the chip and the rake of the tool. Results of simulation for both conventional and vibratory turning show that the dynamic stress intension factor is 1.45 times or more in vibratory turning than that in conventional turning. It is the stress wave that leads to the accumulation and concentration of stress, the dislocation pile-up, facilitating the chip generation and development.
