- 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。

FEP2
- FEP2程序是一个具有通用性的教学程序,可用于计算一般的线性静力学问题。目前它已设计了平面梁单元与平面3-9个节点的两种单元,但留下接口,可以接入所设计的其他类型的单元。该程序可以处理多种工况、多种类型单元组合结构问题。同时,还可以处理固定约束和指定位移的情况。其主控程序的功能主要有以下几点:(1)内存分配;(2)网格生成;(3)变带宽存储设置;(4)单刚的形成与组集;(5)刚度矩阵的分解;(6)形成节点载荷;(7)形成与组集单元载荷;(8)求解位移;(9)求单元应力;(10)求解结构反力。在F
