BUCKLING ANALYSIS OF ANISOTROPIC PLATES USING PERTURBATION TECHNIQUE

A buckling analysis of anisotropic composite layered plates is presented. The analysis employs finite strips in conjunction with a perturbation technique and is applicable to rectangular plates with one pair of opposite edges simply supported. The perturbation technique plays the vital role of decoupling the harmonics characterizing the solution. The perturbation parameter is 6, the ply angle, which gives the orientation of the plies with reference to the plate axis. The technique is seen to be a powerful one, producing rapidly converging solutions over a considerable range of 6. The results obtained using this technique are compared with currently available analytical and experimental results. © ASCE.
