High von mises stress

http://fatiguetoolbox.org/fatlab/documentation/theory-reference 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.
