1. Resilience (R) as a function of frequency at amplitudes of 0
Resilience (R) as a function of frequency at amplitudes of 0.1 (circles), 0.5 (squares) and 1.0 mm (triangles).
Resilience (R) as a function of frequency at amplitudes of 0.1 (circles), 0.5 (squares) and 1.0 mm (triangles). (A) Fixed-coxa resilience was significantly greater than (B) free-coxa resilience. (C) Using tan(δ) to calculate resilience (black line and open circles) overestimates the actual values (gray line and filled circles) and produces an inverse dependence on frequency because the calculation is based on a linear model. While leg data are well fit by a linear model, the leg data are not linear, and care should be used when applying linear calculations to any biomaterial.
