请问有研究颅脑损伤的吗

zyg1984

我要用ABAQUS做个颅脑损伤模型，但是不知道颅骨和脑部之间的接触怎么定义？是普通的接触还是应该用固定在一起？请各位前辈们指教啊！

你可以在外文论文里面找到相关的资料

滑动接触吧，不过一般是在CSF和DURA MATTER之间

建议你做一个literature review，看看前人是怎么定义的。你可以先用tie算一次，在定义frictionless contact算一次，最后在定义 friction contact，一步一步来，比较小区别，根据你项目的目的来定如何简化模型。

我也研究这方面。。请加个好友一起研究》358680087（注脑损伤）

Please make sure that there is a layer of CSF between skull and brain. Otherwise, your model is invalid no matter how well it correlates the experimental results due to the low biofidelity. Friction between skull and brain is so small that it can be omitted. Human head injury is a quite difficult and complicated problem. Please be careful when it's being dealed with.
