The reduction in structural failures of the facial bones is of extreme importance because of the protective characteristics of the facial bones. This reduction can lead to a reduction in injuries to both the brain and the eye. This report describes a focused effort to determine the tolerance thresholds of facial bones subjected to blunt impact in the lateral direction. A total of 64 tests were performed in the lateral direction using a free-falling mass. Acoustic emission sensors were used to detect the onset of fracture to produce non-censored fracture data. Injury risk functions for blunt lateral impact have been developed for the frontal, zygoma, and nasal bones. Furthermore, a series of 22 matched tests were performed to access the biofidelic and repeatable response for lateral impact to the frontal, zygoma, and nasal bones. Future use of these analyses will aid design engineers in optimizing the development of enhanced face and eye protective equipment
