Yield stress is 280Mpa, yield strain should be 280Mpa\/110000Mpa=0.0025&nbsp;<\/p>\n<p>When I check the Equivalent (von-Mises) Stress and Equivalent Total Strain, I find that only a small area exceeds the yield stress 280Mpa, but a large area exceeds the yield strain 0.0025. <\/p>\n<p>In my understanding, if the material exceeds the yield strain, it should exceed the yield stress too. How to explain this result? I use second order solid element and put 6 elements through the thickness, all stress and strain are averaged display results, Ansys version 2020 R1.
