Good evening all,
I am trying to analyze a part, simulating wind pressure on a large surface.
I have an aluminum extrusion, which is attached to a foam board.
The aluminum has a hinge which attaches to another piece.
So, the hinge would be fixed and the rest of the part is free to move. I want to apply pressure to the board, and I am concerned about the aluminum hinge failing.
First issue, my mesh ratio is too high, and I'm not sure if it is causing the following issue.
I want to apply 30-40 psf to an 8'x8' board. Then trasfer the load onto the extrusion.
For example I applied a force of ~500lb (made it up), but this displacement is only .00106 inches.
The material is 6061-T6 and the thickness of that area is only 0.09"
So it seems to me it's incorrect.
