| Research Abstract |
The mechanism of hip fracture by fall and the effects of hip protector on the protection of hip fracture are elucidated for developing a test system to evaluate a hip protector. Based on the results, we design and manufacture the test system, and evaluate a protector developed by us, and a few protectors commercially available in the marketplace. In addition to these, we perform the analysis to evaluate the risk of hip fracture by backside fall, and find that the backside fall may be more dangerous than the fall under walking. To obtain accurate simulation results we also observe and organize our experimental results on damage properties of musculoskeletal muscle, and formulate constitutive models of the muscle.
