Hi,
I want to estimate the resistant capacity of metallic tubes of circular section subjected to a longitudinal compression and external pressure calculated by the standard EN 1993-1-6, with non-linear analyzes (Geometrically and Materially non-linear Analysis with Imperfections - GMNIA).
I...
when I change the TIME value in the analysis, I get different responses between the analyses.
what is the program procedure?
Attached follows my script.

Right now, I am performing a nonlinear geometric and material analysis on a tube with the application of two loads simultaneously.
I want to understand what the program does when I apply two loads simultaneously, and what are the differences between the method I called STEPS, as mentioned in my...
yes, two things were wrong
1) The arc-length method cannot be used in a multiframe restart. So, I stopped to use this method
2) After completing step 1 of the analysis, I was deleting the loads before starting step 2. I stopped deleting, and the results got better.
I call this script by...
Hi,
I am performing a nonlinear geometric and material analysis by Ansys APDL on a tube with the application of two loads simultaneously with the respective values:
PC = 150 kN (Axial Compression)
PP = 0,26 kN/cm² (external lateral pressure)
Below are the settings for the analysis in Ansys...
I want to get the maximum value axial compression.
Attached is a figure on the general schemehttps://files.engineering.com/getfile.aspx?folder=bade4e9e-aae4-4c21-8478-00723486416b&file=Esquema_Geral.jpg
Hi
Attached follows my script.
1) My last comment:
I didn´t understand what´s happen when I change the lateral external pressure (LEP) to axial compression (COMP).
The value of both SEQV are so different. As you can see, the value of "COMP" are downer than the LEP.
2)
I always got errors...

I think that this should to be the opposit.
What do you think about it...
By Basic Analysis Guide:
Multiframe restart does not support the arc-length method (ARCLEN), reading and solving multiple load steps (LSSOLVE), or nested *DO loops.
That´s my problem, the arc-length method have no support to restart the analysis.
Thanks for your attention,
Hello, I need help with my script on Ansys APDL, if possible.
I'm working with two different loads applied to a tube and because of that I need to perform two non-linear analyzes (Geometrically and Materially non-linear Analysis with Imperfections - GMNIA) in sequence.
Basically I...
