| 摘 要： | 在结构的有限元分析中,不管是线性或非线性,目前广泛采用的仍然是假设位移函数,并以节点位移作为基本未知量的位移法,而广义应变法则以广义应变作为基本未知量。

| Abstract: | In finite element method the Total-Lagrangian (T. L) and Updated-Lagrangian (U. L) formulations are usually based on the displacement method. In this paper approximate equations are formulated by using the generalized strain method developed by professor Chen Baiping. The larg-e deflection analysis of clamped and simply supported rectangular and square plates under uniform load has been calculated by the above approach. The numerical results are compared favorably with other known solutions and experimental results. |
