Glass Failure Prediction for Arnold Engineering Development Center
Abstract
An assessment of expected window breakage at the Arnold Engineering Development Center in the event of an accidental motor detonation at either the J-5 test site or the proposed J-6 test site has been conducted. Motor detonations equivalent to 30,000- and 20,000-lb TNT were considered at the J-5 test site, and a motor detonation equivalent to 100,000-lb TNT at the proposed J-6 test site was considered. A dynamic failure prediction model based upon a Weibull strength distribution was used to estimate probabilities of failure for window glass plates acted upon by anticipated blsst waves that would occur in conjunction with such accidental motor detonations. In the event of an accidental motor detonation at either of the sites, considerable window glass breakage would result. Breakage that would result from an accidental motor detonation equivalent to 100,000-lb TNT at the proposed J-6 test site is expected to be less than breakage that would result from an accidental motor detonation equivalent to either 20,000- or 30,000-lb TNT at the J-5 test site. This study concludes that the proposed J-6 test site is located adequately so that an accidental motor detonation would result in no more window glass breakage than would be expected from an accidental motor detonation at the J-5 test site.
