摘要:	本文將高階層板理論應用於雙模數積層板的有限元素法分析。於單層及兩層雙模數積層板的分析中,與理論解及其他有限元素法比較,本法皆可得到很準確的位移分析及中性面位置。並可明顯地發現本法使用高階板理論,故較一階板元素所得結果精確。 A higher-order shear deformation theory is used to analyze laminated plates for buckling loads. It is worth to point out that since the displacement field used in the formulation of the composite plate element contains higher-order terms, the external work is considered here not only done by the in-plane force but also the virtual force terms relating to the higher-order displacement terms. A displacement finite element model of the theory is developed, and applications of the element to buckling load of laminated plates are discussed. The accuracy and efficiency of the formulation is validated via problems with available exact solutions and other finite elements. Excellent accuracy and fast convergence are observed.
