Having set the Material Non-Linear Model option, the actual stress-strain relation, defined by means of tables ISTROP and SIGEPS, can be reported in a Sigma-Epsilon diagram.

Both tables PIPEMAT and PIPEPLS have an extra button in the table toolbar.

Standard toolbar:

NoSigmaEpsilon

 

Sigma-Epsilon toolbar:

SigmaEpsilon

An example of a diagram is shown below:

SigmaEpsilonDiagram

Having the graph on screen there is an extra button to export the underlying data to Excel:

Standard toolbar:

PrintCopyGraph

 

Sigma-Epsilon toolbar:

PrintCopyExportGraph

 

Info Calculating material-linear, the diagram will show a straight line.
This also counts for anisotropic materials, because they are always calculated material-linear.
