    Abstract: 本文探討有限元素-轉換矩陣法(FETH 法)於直交異向性積層板的自由扭動分析。FETM法最最後方程式數目為一端邊界的節點自由度數目,故較有限元素法其為整體結構的節點自由度數目降低許多。為了避免FETH 法固有的數值不穩定問題,本文發展修正作法,以減少因轉換矩陣的連乘所引致的誤差,並以一些標準例題證驗本法的正確性。
    The finite element - transfer matrix (FETN) method is extendea to the static analysis of orthotropic laminated plates by using the higher-order plate theory. Their use reduces the number of unknowns occuring in the standard finite element analysis. To avoid the numerical instabilities due to the sequential matrix multiplication, a modified version of FETM method is also presented. The accuracy of the present formulation is demostrated through several benchmark problems.
