My character drives a 1999 Ford Expedition which gets somewhat wrecked with him in it (about 15k east of Albuquerque, NM). In trying to work out what kind of injuries he's likely to have (not clearly stated in canon, since he's not as important as the passenger), I've been looking up crash tests. However, I don't rightly understand what I'm looking at.
This page tells me about femur loads, chest deceleration, and head injury criterion results, but doesn't tell me what they actually mean or which test produced those results. The canon has one of my character's legs stuck, so I'm especially interested in the femur load.
So what exactly is femur load, and how do crash tests determine it? What causes it? Is it the same as/similar to femur axial force?
Thanks in advance.
