Application of Statistical Fracture Criteria to the Problem of Predicting Infrared Dome Thermal Shock Failures

摘要

Two statistical fracture theories are applied to the problem of infrared dome fracture in an aerodynamic heating environment. Theoretical fracture predictions are compared with fracture data obtained from full-scale infrared domes in aerodynamic heating and radiant heating tests. A sample application of a fracture theory in the definition of missile launch envelope restrictions is presented for magnesium fluoride domes. (Author)
