Hi,
I have read through the chapter in the manual about declaring a plastic material property, but I cannot seem to find how to define a non-linear elastic non-linear plastic material, for which I have XY data points (stress-strain) and I know the yield point.
Using the plastic material option, you can define a non-linear plastic material with XY data using plastic strain and yield stress but I cannot seem to find how to define an elastic material which is non-linear from XY data points, or how to define an elasto-plastic material from XY-data points.
Hopefully my question makes sense,
Any tips would be appreciated,
Philip
