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 v = 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.
