Journal of Composite Materials. 2018;52(8):1113-11200021-9983https://hdl.handle.net/10016/31623In this work, the performances of circular single-and double-sided composite patch repairs are compared by computing the maximum stress intensity factor of a repaired surface crack. The three-dimensional finite-element method is used to calculate the stress intensity factor along the crack. The effects of the crack depth, composite patch thickness and patch material on the stress intensity factor variation are highlighted. The obtained results show that the selection of single-or double-sided patches depends on both the crack depth and patch thickness.eng© The Authors 2017Atribución-NoComercial-SinDerivadas 3.0 EspañaSurface crackStress intensity factorFinite-element methodCompositeresearch articleIngeniería Mecánicahttps://doi.org/10.1177/0021998317722044open access111381120Journal of Composite Materials52AR/0000021262
