Notched strength analysis of tensile specimens taken from a thick, filament-wound graphite/epoxy pressure vessel
An experimental analysis of specimens taken from a thick, filament-wound composite material pressure vessel (cylinder) was performed by testing tensile coupons with various semi-elliptical surface notches. The strength of specimens with small notches was found to be notch insensitive. The strength …
