Popis: In this chapter, elastic-plastic stress distributions in human femur bone are calculated analytically. The bone is modeled in the form of a cylinder which exhibits orthotropic macroscopic symmetry. Such behavior is characterized typically for unidirectional laminae with on axis loading. Seth’s transition theory has been used to model the elastic-plastic state of stresses. The cylinder so modeled is subjected to external pressure. The results obtained are compared to cylinders made of boron-aluminum fiber reinforced composite which also exhibits orthotropic material behavior and Titanium which exhibits transversely isotropic material behavior. The 174results obtained infer to the fact that boron-aluminum fiber reinforced composite has a much closer resemblance with the elastic plastic behavior of bone structures and will be a better option as a base material for Surgical implants and prosthetic equipment design as compared to Titanium.
