Hi,

Here an example :

nsol, 10, node(x, y, z), u, y ! node solution (y displacement) in position (x, y, z)

prvar, 10 ! lists variables vs time

plvar, 10 ! Display the graph

Hope it could help

@jean collomb thank you very much.

I tried it, but nothing is plotted

What is the number 10?

And is it possible to use node number instead of node coordinations?

Also is it referring to node coordinates in undeformed?

Farzad,

You can plot strain result in Workbench W/O using APDL command. Please use this instruction. Click on the Solution in Mechanical tree. Click User Defined Result icon. Depends on how your project is defined you can put "EPTO1", "EPTO2, "EPTO3" in Expression and plot strian result. EPTO consider elastic, Plastic and Creep strain. If you plot stress result as well (normal stress result), then you will be able to create stress-strain curve you are looking for. If you want to find other user defined contour available in workbench you can click on Solution and Worksheet icon to find them. As always recommend the answer if it was helpful.

Thank you very much Hamid

Do you mean plotting a contour ? What I am searching for is plotting strains , or forces with respect to Time for example

Yes. When you plotted the contour, if you click on it, then you will see the tabular data is created on the bottom right corner. Depends on how you defined the time steps for the problem, you will see the strain results (time dependent strain results). Extract these results into an Excel file. Do the same thing for stress (Normal stress) and extract the result into the same excel file and then plot it.

It is also possible to create this chart directly in Ansys, However the graphs are not as nice as Excel, So I prefer to work with Excel. You can use "New Chart and Table" function and make everything in Ansys.

By the way if you defined only one time step then this method doesn't work for you!! make sure you have enough time step and increase the load gradually for creating an accurate stress-strain curve.

For creating stress-strain curve, you need to define non-linear material first by using plasticity options avaialble in "Engineering Data". I prefer "Multilinear Kinematic Hardening" . Then increase the load gragually by properly adjusting "Number of Steps" and "Time Stepping".

Thank you so much
