Summary

Creep behavior of a commercial grade of glass-bonded, 94 % aluminum oxide under uniaxial tensile static and cyclic (square wave, R = 0.1 and f = 2 Hz) loads is characterized as a function of applied stress at 1000 C and 1100 C. Creep deformation is measured using laser extensometry by monitoring the relative displacement of flags that are attached to the gauge section of the specimen. Under same maximum applied stress, cyclic loading results in more than a order of magnitude reduction in the steady state creep rate as compared to static loading.
