Tensile Test - Constrains
Tensile Test - Constrains
(OP)
Hi,
i got the following issue:
i want to do a tensile test (technically a compression test) with a model of bone i got. For this i received (by my adviser) the model itself and two additional plates.
I want to attach the bone model to the plates so that i can apply boundary conditions to the plates that affect the bone as well (as in a real tensile test).
how do i define the constrains here? i only need to define a displacement constrain between the upper and lower bone surface and the plates surface, but which one is the right one?
Thank you for any help :)

RE: Tensile Test - Constrains
so i played around and used a tie constraint which apparently works. I set the plates as master surfaces (used 2 different constrains) and parts of the sample as slave surface. Now i wondered how you can force only the very elements of the sample that are right at the master surface to have the same displacement as the master elements.
i tried to solve this by first grabbing roughly the sample`s elements around the plates surface and then apply a position tolerance small enough to only capture the elements right at the master`s surface.
Is this the correct procedure (running a job with this procedure right now) or is a different one better/correct?
Thanks for any advice :)
