Structural analysis of solid ankle-foot orthoses

The results of a structural analysis of an ankle-foot orthosis (AFO) using beam theory with results from a three-dimensional finite-element analysis are compared. Analytical results are then compared to data obtained from a controlled load test of an AFO. Conclusions drawn indicate that while beam theory accurately predicts overall reflections, the finite-element analysis correctly locates compression zones where local buckling may govern the type of failure mode.<
