High stress values occur in … 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. WebNov 26, 2024 · The von Mises stress is always positive, while the hydrostatic stress can be positive or negative. It’s not appropriate to think of the von Mises stress as being “tensile”, as one would if it were a normal stress (with a positive sign). It’s effectively a type of (volume-averaged) shear stress. camping proche plage naturiste bretagne
