title: A finite element approach and experiments to assess the effectiveness of hip protectors.
abstract: The potential of hip protectors to prevent femur fracture is addressed in this study. A mechanical model of the human hip was developed and used to perform impact tests with different types of hip protectors. In addition a finite element model of the test device was established which allows simulations of the impact tests. The different principles of energy-shunting systems and energy-absorbing systems were demonstrated. Furthermore misplacement of a hip protector can be simulated. Hence the FE model was shown to be a suitable tool for future hip protector design.
