Finite element analysis is an alternative way to study human fracture behaviour as the technology is a leading innovation in biomechanics field. The aim of this study is to analyse the strain intensity factor and strain energyrelease rate when three-point bending test and tensile test were applied on a two-dimensional cortical bone model developed and tested using finite element software, Ansys. K values gained from Data Extrapolation Method (DEM) through Ansys for three-point bending test were compared with CINT method, Hiroshi Tada’s and Allan F. Bower’s theoretical expression while K values from DEM were only been compared with CINT method for tensile test. Meanwhile, J-integral values were obtained through CINT method using Ansys and analysed with different crack-to-width ratios and loads. As a result, stress intensity factor increased as crack-to-width ratio increased and strain energy release rate also increased as crack-to-width ratio and loads increased. It can be concluded that finite element analysis can be used to study the fracture behaviour of human cortical bone.
