very different from the expected trabecular architecture for the considered load
case. Therefore, in further studies the same four distinct a parameters will be
considered until a consistent conclusion can be obtained.
Next, the influence of the material anisotropy is analysed. Thus, in this study the
bone tissue is considered as an anisotropic material. The material law proposed in
