TL;DR: In this paper, the Fermi-Dirac distribution is used to model a smoother transition in the displacement and the strain fields of the delaminated interfaces during the opening and closing of the layers under vibratory loads.

TL;DR: In a response to the Columbia Accident Investigation Board's recommendations following the loss of the Space Shuttle Columbia in 2003, NASA developed methods to monitor the orbiters while in flight so that on-orbit repairs could be made before reentry if required.
Abstract: In a response to the Columbia Accident Investigation Board’s recommendations following the loss of the Space Shuttle Columbia in 2003, NASA developed methods to monitor the orbiters while in flight so that on‐orbit repairs could be made before reentry if required. One method that NASA investigated was an acoustic based impact detection system. A large array of ground tests successfully demonstrated the capability to detect and localize impact events on the Shuttle’s wing structure. Subsequently, a first generation impact sensing system was developed and deployed on the Shuttle Discovery, the first Shuttle scheduled for return to flight.
