Abstract :
Finite element simulation was carried out on a dog bone model assuming an elliptical bone cross-section. The analysis was carried out for both undamaged and damaged cases with longitudinal as well as cross-sectional microcracks using a general purpose finite element software (Abaqus). It was found that as the damage parameter increased, the bending stiffness decreased. For the same damage parameter, longitudinal damage was more severe than the cross-sectional damage in the case of bending considered in this study. The same results were obtained in the mode shape studies
