... (mixed mode) and DCB (Mode I) tests were 15% and 23% of the static values, respectively. Fractographic evaluation revealed identical initial failure mechanisms in fatigue and static loading conditions for the ENF specimen. The ENF specimen failed by formation and coalescence of microcracks. The low...

... for three material systems: a whiskerreinforced cordieritecomposite,a fiber-reinforced cordierite composite, and a fiber/whisker hybrid-reinforced cordierite composite. KEY WORDS: composites, ceramic matrix, hybrid composites, microcracking, failure mechanisms, transverse properties The historical...

...TL Norman; C Anglin; D Gaskin The unnotched and notched (open hole) tensile strength and failure mechanisms of two-dimensional (2D) triaxial braided composites were examined. The effect of notch size and notch position were investigated. Damage initiation and propagation in notched and unnotched...

..., flexure, compression, and short-beam shear. The property values are reported and the failure mechanisms under different loading conditions are identified and compared. The elastic properties of the knitted composites are analyzed by geometric modeling followed by the finite element analysis (FEA). Good...

... shear cut-off predicted by most anisotropic strength criteria for composite laminates under a biaxial tension-compression stress state is not observed in G-10 composite laminates. KEYWORDS: composite laminates, biaxial testing, failure strength, failure mechanisms, woven laminates Uniaxial tensile...

... in a carbon/epoxy laminate, which displayed little pullout. KEY WORDS: composite laminates, carbon/bismaleimide, scanning electron microscopy, failure mechanisms, tropical exposure Recent work by the first of the present authors characterized the flexural strength and fracture toughness behavior of carbon...
