Abstract
Linear viscoelasticity theory was used in the formulation of a general buckling theory for fiber-reinforced composite laminated plates. The theory includes the effects of transverse shear and normal deformation (TSD and TND, respectively) and bending-extensional coupling of time-dependen t buckling response. Anisotropic viscoelastic constants were determined using the Tsai-Halpin equations, assuming elastic fiber properties in combination with a power law viscoelastic model for the matrix properties. The governing equations of plate buckling were developed using the Theorem of Minimum Potential Energy, and the Rayleigh-Ritz method was employed in the solution of the governing equations for specific boundary conditions. Results are presented comparing viscoelastic solutions based on classical analysis, analysis including TSD effects, and analysis including both TSD and TND effects for simply supported plate subjected to inplane compressive loading a aT
