Consider the bar above. It is .4 10 inches thicklong, 3 inches wide (w) , the 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.

You can download our 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 half 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).

1. Look at the deformation plot. From this plot, what can you tell about the boundary conditions (displacement constraints and traction) that have been applied to this model?

2. Does the deformation variation look right? Why or why not?

Consider the stress components in a polar coordinate system (r,theta) centered at the right hole.

3. Does the sigma_r variation look right near and away from the right hole? Why or why not?

4. Does the sigma_theta variation look right near and away from the right hole? Why or why not?

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

6. From the above 5 items, can you tell if the ANSYS model provided to you has been set up correctly? If there is an error in the set up, what might it be Look at the sigma_xx plot. There are three distinct regions in this geometry:
a. Away from the hole and symmetric grooves
b. Adjacent to the symmetric grooves
c. Adjacent to the holeWhat are the sigma_xx values you expect in these three regions? What is the % deviation of the corresponding ANSYS result from these values?
