| 摘 要： | 岩土类介质在承受荷载时,不仅产生弹塑性变形,还伴随着渗流和固结,是一个关于时间的动态过程。本文建立起处理该问题的参变量变分原理以及相应的有限元方法,这样将原问题化为求解带约束条件(本构状态方程)的二次规划问题.文中讨论了单元的选取形式及具体的实施过程,还给出了一个实例.

| Abstract: | Geomaturials (e. g. soil) show both elastoplasticity and consolidation under loading, which is a dynamic process of time. The paper studies this problem and presents the parametric variational principle and corresponding FEM for this problem aiming at its numerical analysis, which could be converted to a quadratic programming problem under a restraint condition obtained by the constitutive relations. The FEM matrix formulae of the problem and its inplementation have been discussed. Also. an example has been presented to show an application of the proposed method. |
