[ABAQUS] Displacement analysis spine

[JetSkiS]

Hello everyone,

I modelled a scoliotic spine and would like to displace every vertebra so that the spine looks straightened.
In the visualizaiton mode, I would like to see the reaction force on the displaced vertebrae. So in short, input = displacement, output = forces/stresses. However, I don't know yet how to handle this. For now, I used boundary conditions to displace the vertebrae in a more correct position (e.g. 'move 20 mm to the left in x-direction'). Preferably, I'd like to be able to move the vertebrae along a straight line with x,y,x,dx,dy,dz direction. Does anyone have any suggestions on how to make this work?

Thank you in advance.

You have to use boundary conditions to move these parts but you can apply these boundary conditions for example to reference points connected (with coupling constraints) to the surfaces of the model. Proper amplitude definitions will let you achieve even complex motion.
