摘要: Abstract An exact finite strip for the buckling analysis of moderately thick symmetrically cross-ply laminated composite plates and plate structures is presented in this paper by using First-order Shear Deformation Theory (FSDT). Based on concept that so-called effectively a plate, critical load out-of-plane deflection mode shape are obtained solving Von-Karman’s equilibrium equation exactly. A transcendental stiffness matrix an individual strip. The overall whole section assembling matrices. Since transcendental, it not possible to identify separate geometric matrix. In secure method i.e. bisection used find corresponding structure.
