Abstract
A comprehensive experimental program is performed to assess the fatigue behavior of a self-healing polymer. The inherent fatigue characteristics of the material are measured. A fatigue-life-extension-based protocol is established for characterizing self-healing under a cyclic loading. Retardation and arrest of the fatigue crack result from self-healing induced crack-tip shielding mechanisms and significantly increase fatigue life.
