The estimated material elastic modulus in the finite element (FE) model for the synthetic femur was very similar to available data for this bone analogue. The estimated cadaveric bone modulus however differed significantly from documented values for cortical bone.
A theoretical analysis demonstrated the great sensitivity of the estimated modulus value to the accuracy of the geometric definition. The very low variability found in the experimental test on the synthetic bones together with their more regular geometry and the possibility of achieving greater accuracy in geometric definition enabled the production of a valid FE model of this bone for an isotropic ...
