Consider the bar above. It is 10 inches long, 3 inches wide (w) and 0.4 inches thick. The groove radius r is .5 inches, and the diameter d of the hole is .3 inches. The applied traction is 10,000 psi. The plate is made of A514 steel with a modulus of elasticity of 29e6 and a Poisson ratio of 0.3. Assume plane stress conditions are valid.

You can download our linear elasticity solution in ANSYS solution by clicking here. Unzip the file and load the solution into ANSYS Workbench as in the tutorial. Double-click on Results in Workbench to bring up the FEA results that have been calculated already. Note that our ANSYS solution makes use of symmetry and models the top half of the bar. You might need to change the units for the results display by selecting Units > US Customary (in, lbm, lbf, F, s, V, A).

Consider the stress components in a polar coordinate system (r,theta) centered at the right hole. These stress components are included in the results provided to you.

3. Does the sigma_ Sigma-r variation look right near and away from the right hole? Why or why not?

4. Does the sigma_ Sigma-theta variation look right near and away from the right hole? Why or why not?

5. Does the tau_rtheta Tau-r-theta variation look right near and away from the right hole? Why or why not?
