...JZ Wang; DF Socie Development of a test system and associated experimental procedure for evaluating the strength of composite laminates under an in-plane biaxial tension-compression (BTC) stress state is presented. A description of the BTC test system and specimen is given. Flexible end...

...YS Kwon; BV Sankar Static indentation-flexure and low-velocity impact tests were performed on quasi-isotropic and cross-ply graphite/epoxy composite laminates. The load-deflection relations in static tests and impact force history in impact tests were recorded. The damage was assessed by using...

... as that of a conventional 3-D finite element model. Besides, it provides a convenient format for modeling the 3-D stress fields in composite laminates [ 2 ]. The progressive failure algorithm is based on the assumption that the material behaves like a stable progressively fracturing solid. The stiffness reduction...

... 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...

...MS El-Zein; KL Reifsnider The notched tensile strength of composite laminates was examined. The behavior and prediction of unidirectional off-axis, angle ply, and [0/ ± θ] s laminates is discussed. It was found that good predictions for off-axis laminates can be obtained since the same failure mode...

... laminates, continuous strain model, finiteelement analysis, free-edge effects The analysis of the stress distribution in the vicinity of tractionfree edges of composite laminate strips under uniform extension has received wide attention. It has been found [1] that the high gradients in interlaminarstresses...
