Abstract

In the present study, 2D plane strain finite element analysis of the compact tension specimen is used to analyze mode I crack growth in human bone. Four different methods have been evaluated to determine the fracture toughness parameters Kc, critical stress intensity factor, and Gc, critical strain energy release rate: extrapolation technique; j-integral; crack closure; and crack extension methods. Comparison of each of these methods is made with the experimental results to test their validity. Results indicate that better correlation is found between calculated and experimentally determined Kc than Gc, and for material assumptions consistent with linear elastic fracture mechanics used in the experiments.
