consider the Clevis fork domain (see here for an image https://www.traceparts.com/it/product/camloc-motion-control-h1-stainless-steel-clevis?CatalogPath=TRACEPARTS%3ATP01001005&Product=10-12112014-075680&PartNumber=084337) and the linear elasticity equation on it. What are suitable boundary conditions that can be applied on such a domain? Even the simplest possible ones are fine, as long as they have physical meaning. I tried to search on the net but I didn't manage to find a clear setup!
EDIT:
Let's call $u_D$ the displacement field and $f$ the load (the rhs of the equation). Also, let $A,B$ be the surfaces of the two holes of the clevis (where the pin is passing through) and $C$ the annulus at the front of the clevis.
If I understood correctly:
- $u_D = 0$ on $A$ and $B$
- $\sigma \cdot n=(1e6,0,0)$ on $C$
- $f=0$
What I mean with the second condition is that a traction of $1e6$ is applied on $x-$direction.
Now, I need to provide boundary conditions for the rest of the boundary $\Omega \setminus (A \cup B)$. As the surface is kind of free, I think a homogeneous Neumann boundary condition should be correct, i.e.
- $\sigma(u_D) \cdot n=0$ on $\partial \Omega \setminus (A \cup B)$
Thanks!
