Title: Evaluation of Notched Strength of Composite Laminates for Structural Design

Abstract: The use of notched specimens to generate design allowable is common practice among aircraft designers. This article assesses the limitations of open-hole tests and emphasizes the importance of numerical simulations to produce notched strength data for structural design allowable. Using numerical simulations, failure envelopes of open-hole specimens were obtained for two different quasi-isotropic carbon fiber-epoxy laminates, namely, [pi/4]: [45/90/-45/0](4s) and [pi/3]: [0/+/- 60](5s). It was demonstrated that open-hole tests produce data that is very limited to the specific loading conditions and, therefore, shall not be directly applied to structural design.
