force-displacement curve

I have a pipe with non linear material , internal pressure and a force end of pipe , 2 load step, at the first step I have only internal Pressure and in second load step,Pressure+ Force. I have defined the force as pressure. after analyse I want to get force- Displacement (force end of pipe as pressure ) . I need force-time and displace-time curve but I have only one time . I need many time to get curve. what should I do?

Best regards

Please refer below post for plotting force vs displacement curve using HyperGraph.

thank you mr.Rahul. but i don't know how can i create *.ABF file?! could you please guide me?

thanks and best regards

If you are using Altair OptiStruct or Radioss solver,then you can use .h3d file to plot curve.For other solver, please use a file which contain this output.Please share the solver used for analysis.

hi . i share my file. could you please make for me a force displacement curve for subcase 1 and 2 ? as a result I have to get following diagram :

thank you.

Hi @Saeideh

I am not clear about the analysis and also solver.

I see /RUN card in the model but works with OptiStruct. Please clarify.

hi,

thank you mr Pagadala for your answer.

it is so:

at the first, there ist only an internal pressure of p=2.5 Mpa ( this pressure with a load scale can increase ( incrementally) up to 2.5 Mpa). now i have pressure (p=2.5 Mpa) and I have to bring an axial force (increases incrementally) at the end of pipe up to welding area is plastified. ( as a figure - this force is defined hier as a pressure too) .

best regards

Hi,

OK, thank you,

If you want to plot applied load Vs displacement, you can add OLOAD card to your model which outputs applied load.
