Consider the bar above. It is .4 inches thick, 3 inches wide (w), the groove radius r is .5 inches, and the diameter d of the hole is .3 inches. The proportional limit of the material is 57 ksi.

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

2. 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 hole

Using paper-and-pencil calculations, please determine if the ANSYS solution for What are the sigma_xx values you expect in each of these three regions? What is correct. If the solution is not right, please indicate how it can be fixed. (Note that you don't need to fix it.)the % deviation of conrresponding ANSYS solution from these values?Go to all ANSYS Learning Modules
