Evaluation of Statistical Fracture Criteria for Magnesium Fluoride Seeker Domes.

Abstract

Four statistical fracture theories are applied to the problem of infrared dome fracture in an aerodynamic heating environment. Theoretical fracture predictions are compared with time-to-fracture data obtained for full-scale magnesium fluoride domes in an aerodynamic heating environment. The surface-distributed flaw theory of Batdorf proves to yield the most accurate predictions of the probability of dome fracture.
