Problem 5

Use MSC Marc Mentat to determine stress distribution in the S-shaped block shown. Assume t =0.25 in, E = 10∙106 psi and v = 0.33

Hint: to generate the 3D mesh, first create the curve outline of the cross-section, apply curve divisions, mesh with 2D quad elements, then use the operation “Expand” in the depth (z) direction (translation) to extrude 2D elements into 3D elements. Do not forget to “sweep”. Use at least 2 elements through the thickness
