A Comparative Study On The Stress Intensity Factor Of Carbon Epoxy Composite Plates Having Central Holes

In this paper, a comparative study regarding the determination of stress intensity factors (SIF) for non-standard thin composite plates is presented. Carbon-Epoxy composite plates are considered for the study. Unnotched specimens and specimens containing either 4, 6, or 8 mm dia. holes are prepared...

Zusammenfassung:	In this paper, a comparative study regarding the determination of stress intensity factors (SIF) for non-standard thin composite plates is presented. Carbon-Epoxy composite plates are considered for the study. Unnotched specimens and specimens containing either 4, 6, or 8 mm dia. holes are prepared and then tested. Based on the experimental data thus obtained, two analytical approaches and a finite element fracture analysis tool called FRANC have been used to compare the critical SIF values for this composite material.
