ABSTRACT
In this chapter, elastic-plastic stress distributions in the human femur and tibia bone are calculated analytically. The bone is modeled in the form of a cylinder which exhibits orthotropic macroscopic symmetry. 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 illustrate the stress build up in the bones when there is an external force applied on them, thereby providing insights in the elastic-plastic extensions and their tendency to fracture.
