Comparison of theory and simulation

  When I solve the problem in the picture above, what should I see as the simulation stress value??
  The results are the most similar in average value.
  But the example is cross-sectional and the simulation is volume. It's confusing.

  Hi
  It (max min variation) is because of the stress singularity at fixed location and between them 2 (at contact location) – look at stresses away from these points and say in the middlle of the 2 members.
  Even better is to use beam elements (1D line elements), where this does not happen (singularity). For the right wall (0.4 mm gap) one can usse a translational joint at the end of the copper rod with a stop of x=0.4 mm.
  All the best
