Characterizing the Importance of Free Space in the Numerical Human Body Models

force reaction (for high impact velocity: Peak force = 97 N. com­ pression 49%). The current study shows the importance o f this space on the human FEMs cavities behavior and proposes two configurations able to be used in a future study including detailed FEM. [DOI: 10.1115/1.4029502]
