The maximum von Mises stress is 147 MPa and occurs at the bottom on the symmetry line.

...

Select Stress from the left list, Y-direction SY from the right list and click OK.

Check where the maximum (MX) and minimum (MN) σ_θvalues occur in the plot. The circumferential stress is tensile (positive) and compressive (negative) on the inner and outer portions of the cross-section, respectively. Is this what you'd have expected? Theσ_θcontours are more closely spaced at smaller r values. This agrees with the prediction of curved beam theory that the stress gradients will be highest on the edge nearest the center of curvature.

...

This plots the regions with positive and negative σ_θvalues in different colors. In the red region, 0<σ_θ<200MPa and in the blue region, -200MPa<σ_θ<0. So the boundary between the two colors is the neutral axis.

The FEA results indicate that the neutral axis is curved, contrary to the assumption in mechanics of materials theory.

The radial stress is tensile over the entire cross-section.
