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.

For the tooth implant subjected to loads shown in Figure P7–19, determine the maximum principal stresses. Let E = 1.6 × 10⁶ psi and v = 0:3 for the dental restorative implant material (cross-hatched), and let E = 1 × 10⁶ psi and n = 0.35 for the bony material. Let X = 0.05 in., 0.1 in., 0.2 in., 0.3 in., and 0.5 in., where X represents the various depths of the implant beneath the bony surface. Rectangular elements are used in the finite element model shown in Figure P7–19. Assume the thickness of each element to be t = 0.25 in.
