Validation of Material Algorithms for Femur Remodelling Using Medical Image Data

Figure 6

The projections of the element principal axes in coronal section. The orthotropic axes of each element were determined by three load cases according to the orthotropic algorithm, and only the first principal axis is shown in the figure. The trabecular alignment is also displayed since the first principal axis is the most stiffness axis, which aligns with the trabecula. The magnitudes and the directions of forces applied to the proximal femur in load case 1, 2, and 3 are also shown in the figure, and the magnitude of scale arrow is 500 N.
