Abstract
The effect of open holes on the fatigue behavior of thin-walled composite tubes was investigated. The compression fatigue of tubes with 0.25-in diameter open hole was monitored ultrasonically and extensometrically. It was illustrated that open hole induced bending of tubes resulting to formation and growth of fatigue cracks that rapidly propagated through the damaged region surrounding the hole. Ultimate failure was observed once cracks propagated to the undamaged portion of the tubes. Generally, the tubes exhibited short fatigue lives; however, there were considerable differences in the lives of individual tubes.
