Screw in bone model (modelling questions)
Screw in bone model (modelling questions)
(OP)
hi,
I am testing the stresses in bone around screws mechanically drilled in bone. I drew screw and bone block models in Solidworks and then imported the X_T files in abaqus.
I have a few questions on my model:
1- How can I drill the screw hole in the bone block? I used the merge/cut command, is this the right way to do it?
2- Should I mesh the parts separately or the instance as a whole? I tried to mesh the instance but the nodes of the screw and bone were not connected, how can I fix the problem?
3- How do I define the interaction? It is supposed to be rigid mechanical locking without sliding.
Thank you

RE: Screw in bone model (modelling questions)
2. If you have different part instances they are meshed separately (they do not share nodes.)
3. If there is no relative motion between the two istances (bone and screw) you can define a Tie constraint in the Interaction Module (see Constraints).
Best.
