The Effect of Temperature on the Strength and Fatigue of Glass Rods

Abstract

By the use of an electrodynamic quick‐loading device, the strength of scratched soda‐lime glass rods was measured at various temperatures between − 190°C and 520°C for load durations of 0.1 second, 10 seconds, and 100 seconds. It was found that the strength was highest at the lowest temperature, declined to a minimum at 100°–200°C, and then increased for higher temperatures. Static fatigue was exhibited at all temperatures, being maximum in the region of minimum strength. Comparisons with the results of other experimenters are made.
