WebApr 10, 2024 · Simulation results reveal that the formation and destruction of oxide film are related to contact stress, von Mises stress and tensile stress. The contact stress destroys the passivation film of CoCrFeNiMo high entropy alloy. Then von Mises stress causes plastic deformation on the surface to form oxide films. WebThe first is generally a poor choice for fatigue assessment because the range calculated from the strictly positive history of the von Mises stress does not include any potentially negative part of the stress cycle. The signed von Mises is thus used to mediate this shortcoming, i.e. by applying the sign of the first stress invariant. where . 3. ...
