For a centrally loaded simply supported deepbeam shown below, compute the flexural stresses SigmaX at the x = 0 on top and bottom surfaces. Compare the results with the exact expression: Sigmax = My/I.
a) use beam elements (use the minimum number of beam elements).
b) Use planestress elements.
Compare deflections obtained by both elements.
