I am trying to find out how to identify specified parameters of ductile damage material in its stress-strain curve in Abaqus. I could identify the Young's modulus and the yield stress, but not the fracture energy. How do I identify this in my results?
For now I am simulating a simple tensile test in y-direction on a one-element model (1x0.2x1).
Have you clicked in the Failure/Fracture check box in the Field Output Request and History output request before submitting the job. If don't then first click on the required check box.
Hello Pankaj,
I checked the ENRRT (strain energy release rates) check box from Failure/Fracture. But I can't find the corresponding output in the results.
Have you tried to extract data in the 'XY data from the ODB Field output' in the visualization mode on the respective node or element.
Is there any warning message regarding the output request?
Thank you for your quick response.
Yes, if I checked all check boxes from Failure/Fracture, in the visualization mode there are only initiation criterion outputs (the damage variable, I guess).
Ah, now I see a warning if I check the ENRRT check box: Strain output request le is not valid for some elements in this analysis. This request is switched to the strain measure, e.
I suppose this is necessary for the strain energy release rate output?
