Effect of notch on quasi-static and fatigue flexural performance of Twill E-Glass/Epoxy composite

Finally, it is observed that different notched geometry behave differently for quasi-static and fatigue loading. For composite component subjected to quasi-static load, the failure is mainly governed by stress concentration (local failure) i.e. the notch size is not a significant factor. Whereas for composite component subjected to fatigue loading, the notch size becomes a dominant factor for failure and results to be more relevant than the stress concentration.
