| 1 | A new orthogonality relationship for orthotropic thin plate theory and its variational principle显示文摘The thought how dual vectors are constructed in a new orthogonality relationship for theory of elasticity is generalized into orthotropic thin plate bending problems by using the analogy theory between plane elasticity problems and plate bending problems. Dual differential equations are directly obtained by using a mixed variables method. A dual differential matrix to be derived possesses a peculiarity of which principal diagonal sub-matrixes are zero matrixes. Two independently and symmetrically orthogonality sub-relationships are discovered. By using the integral form for elastic bending theory of orthotropic thin plate the orthogonality relationship is demonstrated. By selecting felicitous dual vectors a new orthogonality relationship for theory of elasticity can be generalized into elastic bending theory of orthotropic thin plate. By using the integral form a variational principle which is relative to differential form and a whole function expression are proposed. | LUO Jianhui 1 , LONG Yuqiu 2 & LIU Guangdong 1 1.

| 2 | Application of the quadrilateral area coordinate method:a new element for laminated composite plate bending problems显示文摘最近,一些新四边的有限元素被四边的区域坐标(QAC ) 方法成功地开发。与用 isoparametric 坐标的那些传统的模型相比,这些新模型对网孔失真不太敏感。在这篇论文,一新基于排水量, 4 节点 20-DOF (5-DOF 每节点) 四边的弯曲元素基于一阶砍为任意的把压成薄片的合成盘子的分析的变丑理论被介绍。它的弯曲部分基于元素 AC-MQ4,高效的 Mindlin-Reissner 板元素由 QAC 方法提出了的最近开发和概括一致条件方法;并且它的在里面飞机排水量地被双线性的形状功能在 isoparametric 坐标插入内推。而且,混合 processing 以后过程,被作者第一建议,再被采用改进压力答案,为特别横向砍压力。产生元素,作为 AC-MQ4-LC 表示了,在所有线性静态、动态的数字例子展出优秀性能。它再证明 QAC 方法,概括一致条件方法,和混合 processing 以后过程是为开发简单、有效、可靠的有限元素模型的有效工具。 | Song Cen Xiangrong Fu Yuqiu Long Hongguang Li Zhenhan Yao | 2007 | Acta Mechanica Sinica2007，23，5： | 6 |
