Solve the following problems using a computer program. In some of these problems, we suggest that students be assigned separate parts (or models) to facilitate parametric studies.

Determine the stresses in the soil mass subjected to the strip footing load shown in Figure P7–18. Use a width of 2D and depth of D, where D is 3, 4, 6, 8, and 10 ft.

Plot the maximum stress contours on your finite element model for each case. Compare your results. Comment regarding your observations on modeling infinite media. Let E = 30,000 psi and v = 0.30. Use plane strain conditions.
