摘要

This paper presents the generic relationship between crack length and fatigue life for cracks repaired with an externally bonded composite patch. We then show that the crack growth rate follows the generalised Frost-Dugdale growth law. A simple methodology for predicting crack growth is also presented and validated by comparison with experimental data.
