TLDR
Using a differential quadrature (DQ) method, large amplitude free vibration analysis of laminated composite skew thin plates is presented in this paper, where the governing equations are based on the thin plate theory (TPT) and the geometrical nonlinearity is modeled using Green's strain in conjunction with von Karman assumptions.Abstract:
Using a differential quadrature (DQ) method, large amplitude free vibration analysis of laminated composite skew thin plates is presented The governing equations are based on the thin plate theory (TPT) and the geometrical nonlinearity is modeled using Green's strain in conjunction with von Karman assumptions To cause the impact due to nonlinear terms more significant, in-plane immovable simply supported, clamped and different combinations of them are considered The effects of different parameters on the convergence and accuracy of the method are studied The resulted solutions are compared to those from other numerical methods to show the accuracy of the method Some new results for laminated composite skew plates with different mixed boundary conditions are presented and are compared with those obtained using the first order shear deformation theory based DQ (FSDT-DQ) method Excellent agreements exist between the solutions of the two approaches but with much lower computational efforts of the present DQ methodology with respect to FSDT-DQ methodread more

Geometrically Non-linear Free Vibration of Fully Clamped Symmetrically Laminated Composite Skew Plates
TL;DR: In this article, the geometrically non-linear free vibration of fully clamped symmetrically laminated composite skew plates is studied. And the authors show that the nonlinear frequencies increase with increasing the amplitude of vibration and increasing the skew angle, which corresponds to the hardening type effect, expected in similar cases, due to the membrane forces induced by large vibration amplitudes.
