Local Buckling of Rectangular Viscoelastic Composite Plates Using Finite Strip Method

Abstract

This article presents the stability analysis of reinforced viscoelastic composite plates subjected to in-plane loading using a finite strip method. The equations governing the stiffness and geometry matrices of moderately thick rectangular plates in the time domain are presented using higher-order shear deformation theory and effective moduli method. The critical buckling loads of viscoelastic plates are determined through solving the eigenvalue problems related to the global stiffness and geometry matrices. The accuracy of the developed model is verified against the results reported elsewhere while a comprehensive parametric study is presented to show the effects of different variables on local buckling coefficients.
