The nonlinear unsymmetrically laminated composite beams on Winkler-Pasternak fundation
Keywords:
Nonlinear equations, composite beam, OPIMAbstract
In this study, Optimal Parametric Iteration Method (OPIM) is presented for large amplitude free vibrations of nonlinear unsymmetrically laminated composite beams on Winkler – Pasternak elastic foundation. Based on von Kárman geometric nonlinearity, on Euler – Bernoulli beam theory and Galerkin procedure, we obtain a second-order nonlinear differential equation with quadratic and cubic terms. Comparison between results of the present work and those of numerical results shows the accuracy of our approach.
