Exercise 1

A steel bar with E=200GPa and a Poisson's ratio of 0.3 is loaded as shown with a distributed load totaling 50,000 N applied to the right end. The bar is 10 mm thick, and other dimensions are give in millimeters.

...

3. Compare the displacement at the right edge (relative to the left) with a back-of-the-envelope estimate. 

4. Make a plot of the Sigma_xx variation in the bar. Deduce the stress concentration factor for the hole on the right from this plot. Compare this to the theoretical value for a small hole in an infinite plate.
