Physical stresses may bring us unhappy experiences, pain and sourness, even worse, the fracture of bones. Tennis elbow is not a syndrome appearing among tennis players. I believe most of us have this kind unpleasant experience occasionally. Pain or sourness accompanies laterally after over-using our muscle in the same region, waking up with a sour arm after overusing the computer last night, for instance. Surveying some papers I find doctors use MRI (magnetic resonance imaging) to observe how stresses build up in the pain region and how severe stresses induce fracture.
In my project, I attempt to simulate these stresses in our muscles and use ABAQUS to look insight how the severe stresses damage our muscles and our bones, maybe. In other words, I attempt to observe how people get hurt, and figure out the part that is the most fragile of our bodies. And relate the ABAQUS results to the MRI figures.

Physics of overarm throwing
As I was searching for more papers, I stumbled across a paper on the "Physics of Overarm Throwing" which show the forces acting on a persons arm when they throw. This might be of some help.
