Abstract

Low-cycle flexural fatigue tests on an epoxyglass-fabric composite were performed at large constant-deflection amplitudes using a modified Tatnall-Krouse plate-bending fatigue-testing machine. Strain vs. cyclesto-failure data were obtained for cyclic speeds of 25, 150 and 425 cpm. The rate of cycling was found to have a strong effect on the low-cycle fatigue life of this composite, but the effect was less pronounced at higher numbers of cycles.
