Abstract
A human FE model which can appropriately represent bone properties and muscle activity is critical for precise prediction of occupants' lower extremity injuries during frontal impacts. In this study, a constitutive model of bones with the anisotropic damage effects and visco-elasticity was incorporated into lower extremity bone FE models and the muscle activity for bracing under the assumed breaking condition was given to a lower extremity FE model with muscular solid model. These models were used for lower extremity injury analysis during frontal impacts.
