Development of practical and simplified human whole body FEM model

A practical and simplified human whole body FEM model was developed. For simplification, bones were modeled by hollow shell structures and muscles and ligaments were modeled by bar/beam elements. To validate this model, frontal/lateral impact simulations were performed referring to known cadaver tests. As a result, it was found that simulation results of bone fracture and impact force agreed well with cadaver tests. This model can be applied to car designs for crash safety and new restraint systems.
