6. Conclusions On the basic of the results of this study, the following conclusions are made: 1- In all notched plates subjected to either static or cyclic loading, the cracks propagate parallel to the loading and the fiber direction, i.e. notch insensitivity. 2- A traditional orthotropic-elastic solution is unsuitable to predict SCF in CFRP plate. 3- CFRP plate has a superior fatigue performance. 4- The strength of bolted joints that failed in a shear-out mode is mainly dependent on the diameter of the bolt/hole.
