2 Biomechanics of Knee Injury Professor N. Chandrashekar Professor J. Medley and Professor N. Chandrashekar

3 Impact Biomechanics The goal of impact biomechanics research is to protect the human body from 'serious' injury or trauma (anatomical rearrangement). The development and design of improved safety requires the test that cannot be done Professor D. Cronin Hybrid III Family Detailed Torso Model Full Body Model Full Body Model with Vehicle Integration Professor D. Cronin
