F401 Prediction of macroscopic properties of vertebral trabecular bone and comparison with Keyak's model

Abstract

This paper presents a numerical study on trabecular bone of human lumbar vertebra by using the homogenization method to predict the macroscopic properties. Series set of micro-CT images of healthy and osteoporotic vertebral trabecular bone is used in this digital image-based modeling technique to develop the microstructure model. The macroscopic homogenized properties that include the Young's moduli and shear moduli was obtained in this study to investigate the change of degree of anisotropy in vertebral trabecular bone. Then, the comparison between the predicted macroscopic homogenized properties and the experimental result performed by Keyak is discussed.
