Abstract:

Necked Pyrex rods were used to obtain the values of uniaxial compression stress on glass. Stresses up to 547,000 psi were measured and some unusual phenomena were noted instead of splintering, the glass failed by giving a coherent mass and at the same time set up tensile waves in the specimen. Light was emitted on failure. No creep was observed either under direct uniaxial stress of between 400,000 and 500,000 psi of 1 sec. duration or in the areas of stress concentration around a cylindrical hole drilled through the point of highest stress. The results of this work tend to substantiate a time dependent plastic flow theory.
