High von mises stress
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 von Mises stress reduces sharply in the surface region, which is more pronounced at high laser intensities at the second spot. The von Mises stress remains almost the same …

WebJun 1, 2024 · The von Mises stress-strain curves of metallic materials at high temperatures is also important [33]. Because it was reported that the relationship between von Mises stress and equivalent plastic strain at elevated temperature can be represented by the power law function [ 34 , 35 ], the proposed model may be applicable as well with the ... WebJun 26, 2012 · It is common to get unrealistic high stresses in thermal-structural problems due to improper (over-constrained) structural boundary conditions. For example, if you take a copper bar and fix it at both ends and subject it to a uniform 40oC temperature rise the stresses will exceed yield.

Pure Shear In … WebApr 7, 2011 · This has been previously done in Ansys, resulting in a maximum von mises stress of 3.82e8 Pa. Everything I have tried in Comsol, however, results in a von mises stress about a magnitude higher (~5.34e9 Pa). This cannot be the true von mises because it would mean the material fails (ultimate stress is 517 MPa), and experimentally I know this is ...
