An understanding of how biological tissues including bone, ligaments and muscles respond to loads that cause the damage. This study attempts to provide a state of the human body look at the applied biomechanics of accidental injury causation and prevention. The simple experiments were made to study dynamically mechanical properties of the hog lower extremities subjected to side impact loading. Results were made comparison with those by Kajzer et al. It is shown that the experimental results is significantly dependent upon impact velocity.
