摘要提出一种新的高阶理论,该理论满足层间位移、应力连续条件,其位移场只有5个未数,同一阶剪切变形理论中位移函数的未知数一样多,由此建立了三角形精化板单元.该单元满足单元间C+1类弱连续条件,其收敛性得到保证,且具有列式简单、计算效率和精度高的优点.

Abstract: A higher order shear deformation theory of composite laminates considering transverse normal stress, which fully satisfied the geometric and stress continuity conditions at interfaces, and a refined triangular element based on it are proposed. There are five unknown numbers in displacement filed same as in one order shear deformation theory. There are five unknown numbers in displacement filed same as in one order shear deformation theory. The interelement C\+1 weakcontinuity conditions can be satisfied，so that the convergence are ensured. Numerical results show that the present element has higher computational efficiency and higher accuracy.

Key words: composite laminates plates high order shear deformation theory refined triangular plate element
