摘要
文献［１］［２］建立了四边形单元的面积坐标体系，本文在此基础上，利用优选的广义协调条件，构造了两个广义协调四边形单元，算例表明这两个单元是收敛的，可靠的。
The theory of quadrilateral area coordinates was presented in references [1] and [2]. In this paper, combined with optimum generalized compatible conditions, two second-order elements are constructed based on quadrilateral area coordinates theory. Numerical results show that both elements pass the patch test and give accurate results, and the element named ACGQ6 is convergent, reliable, stable.
