“…These material properties of femoral bone were taken from the literature [14]. For the cancellous bone, however, a homogeneous isotropic material law was chosen, and average values from the experiments by Bini et al [15] were used.…”

“…Many researches [13,16,[18][19][20][21] have not considered the anisotropy of the femoral bone, although numerous experiments have proven that the femur has no isotropic elasticity properties [14,25,26]. In order to have a realistic simulation of the load distribution in the femur, a description of the bone elasticity properties as exact as possible is crucial.…”

Aseptic loosening of the prosthesis is still a problem in artificial joint implants. The loosening can be caused by, among other factors, resorption of the bone surrounding the prosthesis owing to stress shielding. In order to find out the influence of the prosthesis type on post-operative stress shielding, a static finite element analysis of a femur provided with the conventional uncemented stem BICONTACT and of one with the femoral neck prosthesis SPIRON was carried out. Strain energy densities and maximal principal strain distributions were calculated and compared with the physiological situation. Here, stress shielding was demonstrated in both periprosthetic femora. To determine the areas of the stress shielding, the bone in each FE model was subdivided into three regions of interest (ROI): proximal, diaphyseal, and distal. The numerical computations show stress shielding in the proximal ROI of both periprosthetic femora. Diaphyseally, the femoral neck prosthesis SPIRON, in contrast to the conventional uncemented long-stem prosthesis BICONTACT, causes no decrease in the strain distribution and thus no stress shielding. Distally, no change in the load distribution of either periprosthetic femur could be found, compared with the physiological situation.

“…The cortical bone can be properly modelled as a rate dependent transversely isotropic material (Reilly and Burstein, 1975;Yoon and Katz, 1976) thus this tissue can be considered analogous to a fiber reinforced composite material as has been demonstrated in different contributions in the literature; see for instance Guo et al (1998), Hogan (1992), Katz et al (1984), and Bigley et al (2006).…”

“…This means that the assumption of mechanically isotropic bone tissue is a strong simplification of the problem. The cortical bone can be properly modelled as a rate dependent transversely isotropic material [33,34], thus the cortical bone tissue can be considered analogous to a fibre reinforced composite material [35][36][37][38]. Based on this analogy, the osteon acts as the fibre with the matrix being interstitial bone consisting of old osteon fragments.…”

Cutting operations in bone are involved in surgical treatments in orthopaedics and traumatology.The importance of guaranteeing the absence of damage in the living workpiece is equivalent in this case to ensuring surface quality. The knowledge in this field is really far from the expertise in industrial cutting of mechanical components. Modeling of bone cutting is a challenge strongly dependent on the accurate modeling of mechanical behaviour of the bone. This paper focuses on modeling of orthogonal cutting of cortical bone. The intrinsic anisotropic nature of the cortical bone that makes it comparable to a compos-ite material is taken into account. The influence of anisotropy is analysed comparing this behaviour with an isotropic approach. It is shown that both chip morphology and temperature are affected by the anisot-ropy of the cortical bone that acts as a workpiece.
