Rotational spring element #49

Closed NickN-Eng closed 2 years ago

NickN-Eng commented 4 years ago

Hi epsi1on,

Is there a way of achieving a spring in rotation only? I.e. between 2 nodes: Dx, Dy, Dz - fixed Rx - kNm/rad Ry - kNm/rad Rz - kNm/rad

I see that there is already the spring1d element, but it seems like that is for translations, not rotations? Apologies, I am not familiar enough with FEM theory to know.

Yes you are right, I think i should add such spring to BriefFiniteElementNet.CustomElements

I think this is good starting point https://opensees.berkeley.edu/wiki/index.php/Two_Node_Link_Element
