| Abstract: | A materially nonlinear analysis of laminated composite plates is presented. The Reissner-Mindlin type plate theory and a fully three-dimensional elasticity theory of laminated composites are used to analyze the bending of plates under transverse loads. The modified Ramberg-Osgood relationship is used to compute the principal elastic moduli in each lamina. Results are also presented using the modified elastic-plastic criterion of Hill. The results agree well with those available in the literature. Many of the results presented here should serve as references for future investigations. |
