Fig. 1 shows the results obtained from the finite element
model analysis. The critical results indicated are that the
natural frequency (mode 1) for the femur is 23.574 Hz and
12.085 Hz for the tibia. Fig. 1 also visually shows the degree
of deformation for the tibia and femur sample under the first
bending mode. It is clear that the majority of the deformation
takes place in the center regions of both samples.
