Every day people have a car accident and safety in the car becomes more and more an important requirement. Crash safety tests are still used today to understand how safe the vehicle is for the occupants, and which improvements can be made. Furthermore, they are very expensive and limited in predict injuries, so companies have begun to aim for another approach, the Finite Element Method (FEM). Total Human Model for Safety (THUMS) was introduced in computer analysis of vehicle collision. It is a human body computational model, which allows simulating the behaviour of the human body during impacts, giving a more accurate injuries prediction than rigid dummies tests.
