Hello everyone!
I am doing a static analysis in Abaqus. It's a quite simple model. Two plates connected through to holes using rigid body connections (see attached image). One plate is fixed and the other one is loaded. I would like to get in the results the load going through the reference points that I've used for the definition of the rigid body constraints.
I've tried many things; for example, creating a set with the reference points and ask in the history output reactions, total forces, etc. And I get zero force results, which makes sense since the point is in static equilibrium. I've also tried to ask the section forces, but apparently is not a valid result for my reference points.
Any suggestions?
Thanks in advance!
Hi Eladio Hurtado,
You can use obtained displacements and rotations at reference points as boundary conditions prescribed at these points and repeat analysis (with these additional BCs and the same loadings). Results will be the same, but reactions at reference points become available.
Victor J. Аdlucky thanks for your response. This is just a dummy model to try to get the forces results, but I'm working on a larger model with hundreds of these connections and many cases. For this reason, I'm hopping to find a way to extract the forces directly and not doing an additional model with the displacements.
Maybe the next quotation from manual will be helpful: "MPC constraint forces are not available as output quantities. Therefore, to output the forces required to enforce the constraint specified in an MPC, you should use an equivalent connector element. Connector element force, moment, and kinematic output is readily available and is defined in Connector element library."
