[Investigation in the dependency of stiffness of cancellous bone on apparent density--based on the combination model of rod-rod structure and perforated plate structure].
The structure of cancellous bone is cellular. There are two basic models of cancellous bone structure namely the model of rod-rod structure and the model of framework of perforated plate. This paper presents several models of structure developed from the model of rod-rod structure to the model of framework of perforated plate. We computed the elastic modulus of cancellous bone based on these modes using homogenization. The relationship between the elastic modulus(E) of cancellous bone and the apparent density(p) was determined to be E = 1.78rho1.88.
