Abstract:

This report documents the extensive work done on the lower leg finite element model, specifically on the sensitivity of injury prediction on linear elastic material parameters that are chosen within a range of values typically used for biological tissues. Using simple criteria, we predict a variety of injuries typically observed in theater. We find a strong dependence of these predicted injuries on the soft tissue properties included in our model. We also report on a potential oversensitivity in our model to predicting talus injuries. We conclude that biological variability in measured material parameters will need to be accounted for in future models.
