A Study on Development of a Human Pelvis FE Model by Applying in-vivo CT Information of the Human Coxal Bone 2006-01-0463

Construction of a human pelvis finite element (FE) model with high bio-fidelity is a crucial step for achieving reliable prediction of pelvis injury due to impact loadings. Several human pelvis FE models have previously been developed and improved to investigate pelvis injury mechanisms. However, an important aspect to directly acquire heterogeneous bone material properties from in-vivo computed tomography (CT) information has not been extensively studied. In this research, a new human coxal bone FE model was constructed from in-vivo CT scans of a Japanese adult (age 25, 173 cm, 60 kg). And, heterogeneous material properties such as Young’s modulus and yield stress were deduced from in-vivo CT information of the Japanese coxal bone by using the relationship between CT Hounsfield value and bone density, in an effort to apply the obtained in-vivo material properties for a human pelvis FE model.
