Description
Summary:The combined effects of temperature and humidity (termed hygrothermal) are included in a general laminated composite plate buckling theory formulation based on the Theorem of Minimum Potential Energy which accounts for transverse shear and normal deformation and the bending-extensional coupling exhibited by non-symmetrically laminated composite plates. Parametric studies are carried out for symmetrically laminated T300/5208 graphite-epoxy plates with simply supported and clamped edges under both steady-state and transient hygrothermal conditions. Results are presented which show significant reductions in the applied surface tractions necessary to buckle composite structures due to these effects.
