A SIMPLE ELASTICITY SOLUTION FOR PREDICTING INTERLAMINAR STRESSES IN COMPOSITE FLEXBEAMS

A simple iterative method for approximate solution of boundary value problems is presented. The method is applied to the prediction of interlaminar stresses in composite flexbeams subjected to axial tension and torsion loads. One- and two-term closed-form approximations for the stress functions are obtained. The model predictions are compared with results of a finite difference solution, another analytical solution, and a finite element cross sectional analysis.
