1、实例：最简单的杆件单轴拉伸，材料本构模型采用线弹性模型，E206000MPa, =0.3。左端约束，右端施加均布力q=1。Author: xueweek希望这个小例子能帮助初学者减少一两天的摸索时间1材料本构模型：=E在 Property 中定义材料时，在General 下选中 UserMaterial ，输入 206000，0.3。以上两个数值代表E、，在用户子程序中代表着PROPS(1)、PROPS(2)。然后在 General下选中 Depvar，由于该例子中没有使用状态变量，因此在第一项中输入大于0 的数值即可。名师资料总结 - - -精品资料欢迎下载 - - - - - - - -

3、再介绍） 。完成后，点击submit 即可进行分析。3结果以下两张图分布是用户子程序和ABAQUS 自带的材料模型得到的应力云图，可以看出两种图形完全相同。名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 2 页，共 26 页 - - - - - - - - - 4UMAT 子程序对于初学者来说，需要注意的是，FORTRAN 对于程序语言格式上的要求。例如，对于FORTRAN 语言， 前六个字符必须空出来，等等。 检查语法最好的方法就是在FORTRAN 编译器上进行编译。 SUBROU
