【摘要】

：

Cosserat 连续体理论被广泛地应用于材料应变局部化的模拟当中.Cosserat 连续体理论引入了偶应力，增加了本构方程的复杂程度与变量数量，为弹塑性有限元数值实施带来了巨大的代数运算工作量.针对上述问题，本文首先将Cosserat 连续体边值问题转化为泛函求极值问题.

关于FLAC3D和ABAQUS在边坡稳定性分析中的比较

在土木工程中,FLAC3D 和ABAQUS 均是CAE 数值仿真软件,为研究两种软件在工程分析中的适用性,本文采用两种软件对开挖卸荷后的粘土公路边坡稳定性进行数值仿真分析。为保证结果的真实性、有效性,分析过程中均采用强度折减法计算边坡安全系数,同时对开挖边坡附近区域的点进行应力场和位移场的监测。
