Abstract
An automated crack detection system and method for determining a crack initiation potential of a vehicle closure includes a vehicle closure operatively mounted to a vehicle. One or more specific locations on the vehicle closure are identified for monitoring and one or more sensors are mounted on the vehicle closure at the one or more specific locations identified. A signal analyzer assembly is linked to the one or more sensors for receiving acoustic emission signals therefrom when the vehicle closure is repeatedly opened and closed. The signal analyzer assembly compares the signals received to a predetermined threshold to determine a crack initiation potential of said vehicle closure.
