1. Determine the stresses in the member with a re-entrant corner as shown in Figure P7–17. At what location are the principal stresses largest? Let E = 30
10
6
psi and n = 0:25. Use plane strain conditions.
2. 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 n = 0:30. Use plane strain conditions.
