Dynamic and Static Fatigue of Silicate Glasses
Abstract
Fatigue of silicate glasses was studied using both static and dynamic tests. Static fatigue data for acid-etched, soda-lime-silica glass determined at 74F in atmospheres of 50 and 100% relative humidity could be represented by a single universal fatigue curve. The UFC for acid-etched glass does not lie on the UFC of Mould and Southwick which was determined for abraded soda-lime-silica glass, the acid-etched glass being less susceptible to static fatigue. On comparing the fatigue behavior of acid-etched, soda-lime-silica glass to that of pristine E-glass and fused silica fibers, little difference was found in the susceptibility to static fatigue. In addition, dynamic fatigue data for a wide variety of silicate glasses (soda-lime-silica, E-glass, pyrex, and fused quartz) was compared to fundamental crack velocity data for these glasses utilizing the dynamic fatigue theory of Charles. Agreement was good on both a quantitative and qualitative level. The theoretical implications of these results on static and dynamic fatigue are discussed.
