要約

An analytical method for computing the stresses was developed to predict failure of pinned loaded composite joints using the characteristic curve model. The characteristic dimensions required to evaluate the joint strength were analytically computed from stress functions without experimental tests. The Coulomb friction was assumed to act between the pin−plate contact region, and the stress functions required to compute the stress were obtained from displacement expressions that were presented in terms of trigonometric series. Two different graphite/epoxy laminates were used in the analysis to evaluate the joint failure for different joint configurations. The method of analysis was confirmed to be adequate by the good agreement between experimental data and analytical results.
