Performing nonlinear analysis by Ansys APDL with the application of two loads simultaneously
(OP)
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:
TIME,150
NSUBST,50,1000,10
ARCLEN,ON,25,0.001
ARCTRM,U,25,0,UX
AUTOTS,OFF
The relationship between the two loads are quite different.
What precautions do I have to take when working with more than one load?
When I applied TIME,150 what is the program procedure with PP loading?

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.

Is this a static analysis? What are your material models? Anything that is time or rate dependent? Creep, visco, etc?
