I am not an expert in finite element models (FEMs), however, I am reading related articles and trying to find the boundary conditions for knee joint including the bone and cartilage.

Does anyone have any suggestion? How can I find the boundary conditions for the knee joint?

If there any platform or an atlas guiding on different material properties, I would really appreciate if you guide me on this or share any information.

Thanks

如果不进一步了解模型的范围,这是一个无法回答的问题。

如果您正在对整条腿进行建模,并且只想查看上下部分的相对运动,则可以将所有自由度固定在髋关节处。

关节本身很复杂。有接触和相对滑动。你打算包括这些影响吗?

您将应用什么样的负载?这可能是一个小应变、大旋转问题。生物学是非线性的。

什么材料?骨?人工膝关节?肌肉?皮肤?有哪些属性?什么材料模型(例如弹性、不可压缩、小应变或大应变等)?
