Abstract:	於直交異向性複合材料積層板分析中, 高階板理論之位移有限元素法有層問橫向剪應力不連續的缺點,其可以部分應力模態有限元素法改善之。本文將整體-局部觀念應用於部份應力高階板元素以增加計算效率。於已有彈力解之直交堆疊積層板分析中,因本法在局部區域改善了沿厚度方向橫向剪應力分布,故可得準確度介於純粹位移法與純粹部分應力模態有限元素法之間的位移分析,亦可得到滿意的應力分析。 In the analysis of laminated plates, the interface traction continuity can not be satisfied by using the displacement-based higher-order plate element. This drawback has been overcome by the partial hybrid stress method. The global-local formulation is further applied to increase the efficiency of computation.
