Capturing accurate stresses in a bolted joint
-
-
Hello Everyone!
I was practicing a simulation for a simple bolted joint, under shear loading (geometry provided by the Ansys innovation course itself). However, during post-processing I noticed a significant difference b/w the averaged and unaveraged Von-mises stresses.
I tried scoping the stress results on Bolt shank only, but there is still a stress concentration at the location where bolt head and its shank meet (sharing screenshot).
 I tried using adaptive mesh convergence as well, but the stresses even increased. Makes me think if this bolt head-to-shank surface is a stress riser or simply a singularity? How should I address that...
