Occupant Extremity Loading in Frontal Motor Vehicle Impacts: Prediction of Potential Orthopedic Implant Failure Available to Purchase

The analysis of motor vehicle impacts and the resulting injury exposure to occupants with artificial joints can be correlated to a parameter referred to as delta-v. The delta-v of a vehicle involved in a motor vehicle impact is defined as the change of velocity of the vehicle at its center of gravity during impact. The delta-v is a function of the closing speed between the two vehicles and the mass of each vehicle. A general formula for delta-v is as follows: Where: V_c – closing speed between the two vehicles; ε – coefficient of restitution; m – mass of each vehicle.
