nonlinear analysis. Large Deflection in a aluminium sheet
nonlinear analysis. Large Deflection in a aluminium sheet
(OP)
Hello everyone:
I have a problem with a nonlinear analisis.
I have a aluminium sheet, with a small thick, that is someted a pressure at the top. Also I have the curve stress vs strain.
I want to obtain the stresses and deformations of the sheet, but, when I do the Solve, the program doesn´t finish.
I think, that is because, I must put the pressure by increments, but I don´t know how to do it well.
I asked every people I know, who works with ansys,but a few people, works with nonlinear analysis, so I need help.

Are you working in classic or workbench?

It do nothing, doesnt finish the graphic, for that I supposed that the problem is with the pressure.
In the file ERROR, I have a lot of warnings. I send you one of the file and you can see them, because I´m doing many tests, trying to obtain the solution.
Now I´m trying to do it, dividing the load in 10 steps.
Thanks
Ahhh I´m working with classic, no workbench

I thought in some errors in the constrains, but I dont know where, and also maybe, in the calculations about strain and stress...
But first, I´ll try with this tutorial, Thank you very much.
