Analysis of Cortical Bone Fracture in Human Thigh Segment Through Finite Element

Abstract

Stress intensity factor, K, and von mises stress have been obtained by using three-point bending test in twodimensional (2D) model of cortical bone in human thigh segment. This test has been done in finite element analysis (K) with respect to the continuum mechanic approach. The K values obtained from the Ansys simulation is almost similar to the K values of the equation. The differences values between them were in between 0.02% to 6.64%. The values obtained in von mises stress increases whenever the crack length decreases, while the maximum value obtained when the crack length is 1mm. The values of K is directly proportional to the ratio of crack length, where whenever the ratio of the crack length over width increases, the K values also increases.
