La RD dans le patch et dans la plaque à l'interface des plis 0//90 semblent négligeable devant l'extension importante de la RD dans les autres interfaces. L'interface entre les plis -45, 90 de la plaque et celle entre la plaque et le joint collé sont les plus affectées. La RD dans l'interface -45

Les-signaux-d-'ea-(-figure, 22) ont montré que la rupture finale s'accompagne de tous les types d'endommagement localisés plutôt dans les zones C, B et D autour du trou, ce qui correspond bien aux images illustrées à la Figure IV.49. En outre, la fracture sur les faciès de rupture de la réparation par les patchs [90] 4 (Figure IV.14) ne dépasse pas de ces zones.
