Apply load between two moving points

[venkatkv90]

Hi everyone,
I am relatively new to Abaqus, and have never used any subroutines or Fortran codes in it. I basically just work with the GUI.
I have model in which I have to apply a known constant load along the line between two points, each on a separate body (Similar to tension in a string). The points are fixed on each body, and as the bodies displace due to the load, the load has to maintain its direction and magnitude along the line between the two points.
The problem is somewhat similar to having a linear spring between two points on two bodies, except that instead of a spring constant, I have a constant force.
Can anyone please tell me how to model this?

Thanks in advance.

Hi,

Try to use connector element (type AXIAL or CARTESIAN) with force-controlled actuation (*CONNECTOR LOAD).
For details go into Abaqus documentation:
- Abaqus Analysis User's Manual, Elements, 31.1.5 Connection-type library
- Abaqus Analysis User's Manual, Elements, 31.1.3 Connector actuation,

Best,
Bartosz

I tried applying the load using a local coordinate system, but as I understand from going through this forum, coordinate systems do not move in Abaqus, and therefore, my model is not correct.
Also, is there any method to investigate the load in the results pane, so that I can verify whatever I model?

Thanks again.
