之前使用学校的自动升级程序安装的 Abaqus 6.14.3 居然没有自动连接 Fortran 编译器,导致使用用户子程序的时候发生编译错误。试了好半天才找到解决办法,记录备查。

Here is an example of VUMAT using Hashin criteria for composites. Rumors said it was from the company. This is re-posted from nabble.com. I have not test it. And I also found the same VUMAT in the appendix of a PhD thesis (please refer to the foot of this post).
Because of carelessness, I ran into a ‘problem during linking’ error in Abaqus. The mistake was misspelling a dimensional variable name. That caused the variable used had not been declared.
VUMAT can be implemented to a model which has more than one user custom materials, using cmname variable to identify the materials.
如何在 VUMAT 中确定处理的 Element 的序号?这是个有趣的问题。在 polymerfem.com 找到一个方法并附有解释。记录,暂无验证。
