Abstract : The ASD program to obtain useful, statistically sound, design criteria on optically transparent window materials of a brittle nature and suitable for military air vehicle applications is summarized. Several factors associated with the determination of Young's modulus and the modulus of rupture for seven commercially available glasses are presented and in interpreted. The practical strength of plate glass is dependent on several factors including surface finish, thermal conditioning, cutting techniques and composition. Effects of these variables together with long and short time elevated temperature strength capabilities are shown.
