When recording operation using Macro Manager in Abaqus, some operations are showed using commmand “getSequenceFromMask”. It is totally unreadable. So we need to tell Abaqus to record this kind of operations in other manner.
For a Traction Separation interface behaviour, there are three property values to be set: E/Knn, G1/Kss & G2/Ktt. I am looking for the method to determine/calculate the values.
Abaqus 中提供了两种方式来模拟界面问题：1. cohesive element；2. surface-based cohesive behavior。其中后一种是在界面的两侧的两个表面之间定义一个相互作用（interaction）来模拟界面特性。
Typically, Abaqus has two methods for simulating the bonded interface behavior between two entities. One is Cohesive Elements, and another is Surface-based cohesive behavior. When thickness of the interface is negligible, surface-based cohesive method is recommended for its convenience and effectiveness.
VUMAT can be implemented to a model which has more than one user custom materials, using cmname variable to identify the materials.
To obtain more insight into the stresses and strains of a loaded structure we may want to view results along a line rather than a point. This can be achieved by defining a path and then plot throught the path.
Abaqus 早期好像是只有通过命令行提交任务的。即使到了现在，很多人还是喜欢直接通过命令行操作。而且有时候需要用命令行提交 inp 文件进行计算还可能是因为少数 keywords 不为 Abaqus/CAE 识别。
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。
Abaqus 可能会提示有些 Elements 出现了过度变形，并提示可以通过 element set ErrElemExcessDistortion 查看。即使该模拟中途因错结束，也可以在输出中查看到这些单元。
默认的灰色很不方便。
更改位置：Options -> XY Options -> Chart 打开 Chart Options 对话框。
最下面的 Fill 前面打勾为应用背景色，不打勾就透明。Fill 后面的颜色就是背景色，单击可打开调色板更换。
