Calculations for the load 10 times greater

As the stresses for normal load were small, it had to be checked when the stress exceeds the yield value.

Graphs, shown below, were based on the point marked in the picture above.

The result of above analysis for the load 10 times greater than normal shows that maximum stress exceeds the yield value for only about 2 MPa. Stresses are still greatest in the areas of support. What is interesting graph of the stresses for the tested point becomes nonlinear at 44MPa which is hard to explain.
