Hello everyone again!!!
I Have not been able to resolve the nonlinear problem.
Can someone tell me any elements types, which I can use in this type of problems?
Because, I tried with shell 181 and Plane 42
the problem is nonlinear, with plasticity. I´m trying to analize a sheet ( 1x1x0.1m)...
Thanks timKwan! I go to do this now.
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.
hello, again!!!
well, i tried to do the substeps, first with 3MPa of pressure, divided into 10 step, and after, 2Mpa, into 15 step...and nothing.
The ANSYS says: LSSOLVE looping is stopped because solution is unconverged and NCNV,1,set.
Also, says that some elements have a Excessive...
Hi!!
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...
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...
