1.本程序为平面变形问题非线性有限元程序,可用于计算土坝、地基、挡土墙或地下结构的应力和变形。
2.土的非线性应力--应变关系采用邓肯双曲线模式
另一个弹性常数可有两种选择:
(a)切线泊松比:
(b)切线体积模量:
3.解题方法为中点增量法,考虑到每级加荷的两次计算所得的弹性常数对某些单元可能相差较大,而实际可能处于这两者之间,因此取两者的某种加权平均值作为修正的计算弹性常数,其中初始弹性常数取权为1/4,中点弹性常数取权为3/4,以反映平均结果接近中点弹性常数。

ABAQUS中用户材料子程序UMAT的开发主要解决两方面的问题:本构模型的建立和积分算法的选择。
本文主要研究非线性材料的UMAT实现方法,并重点研究其迭代算法部分,目前,用户材料子程序UMAT的迭代算法主要是常刚度法,常刚度法的优点在于算法原理较简单,程序编写较方便,缺点是当遇到复杂非线性材料时,其迭代次数较多,收敛速度也较慢,在这个情况下,本文采取的是一种迭代次数较少且收敛速度较快的切线刚度法,具体就是采用FORTRAN语言编制了基于Von-Mises模型的接口程序,并采用切线刚度算
