Running a bending simulation
I have two pipes, one inside the other. the inner pipe is made from a surface extrusion using a cylindrical shell, i.e. it has no thickness, and for the sake of this study it has to be (as this is the only way to apply anisotropic properties to a cylinder). I am trying to bend the outer pipe only through 90 degrees to analyse where the inner pipe buckles or deforms. A static study will not allow for large deformation, and buckling/non-linear studies do not work as when I try to run it it says one body has no thickness. I was wondering is there any way to run this study? I attached photos of the set up, as well as a diagram for what I'm looking for. This is all done through SOLIDWORKS. Many thanks
Accepted answer
Depending on what phenomena you want to capture, one possibility would be to study a small sector of the tube, since most likely the entire elbow works in similar conditions.
This would allow you to evaluate smaller "displacements" and have a lower computational cost. Probably the "deformations" can be large and perhaps enter the plastic period, so you will need to apply a suitable material behavior law (but not before testing in elastic regime).
