垫片单元（GASKET）设置问题

ubunt1

RT，想请教下各位大神，ABAQUS垫片单元设置的问题，尝试了好多遍还是不行。请大神指教加载和卸载曲线应该怎样填写啊。
如图给出压缩回弹曲线（线压宽度为0.2mm）

你打算用three-dimensional line gasket element还是  three-dimensional gasket element？

垫片单元还分这两种么？我也是才接触垫片单元。

如果你只关心垫片厚度方向的行为可以使用GK3D8N或GK3D12MN单元。你可以参照这个inp文件来设置，同时看一下abaqus帮助。

十分感谢，这个模型会帮我大忙的，请问有没有模型的背景能不能给我粘贴一个？另我做密封性分析，垫片模型（如上图）是只做筋模型么？还是需要带筋的垫片？（水泵密封垫片，模型为突起的垫片密封筋）

楼主，您好，我现在也在做垫片的模拟工作，可以留个QQ一起交流下吗

这么好的帖子。
楼主最后怎么解决的，ABAQUS帮助中的例子，没有循环加载，只有单次加载和减载的曲线。
同问，循环加载的曲线应该怎么在ABAQUS里面加？

你好，我想问下three-dimensional line gasket element怎么设置？
