Let's say I try to simulate a compressive force on an ellipsoid tubular made of composites (ex.: bicycle frame).
For the moment I'm beginning with a very simple model, a 2D section profile of that ellipsoid shape (like a "0") with a force coming from the top and pressing down.
If I assume that I have about 10 layers of evenly oriented composites sheet (no 90/45/0 directionality yet, I'm starting simple) that have been formed to shape, how do I apply my (x,y) material coordinates so that they follow my surface profile (i.e. y-coord would stay normal to the surface instead of globally vertical)?
Do I need to create a Mapped System for that or is there a simple way to define a material as a "formed sheet" where y-coord properties are always normal to the profile surface regardless of the shape I use?
(I'm just beginning with COMSOL so I still have a lot to learn!)
Thanks.
