The Failure Characterization of Composite Pinned Joints

Abstract

An analytic model was developed to predict the failure strength of pin loaded composite joints using a two-dimensional analysis. The characteristic dimensions, which define the characteristic curve, were obtained by stress analyses associated with no bearing and tensile tests on laminates with and without a hole. The available experimental data in the literature was then used to evaluate the joints’ strength. There was a good agreement between the experimental data and the computed joints’ strength. Additionally, the failure mode that characterizes the failure condition depends on the orientations of the laminas that constitute the laminate used for joint construction.
