Hi,

I'm modelling a bonded joint using the VCCT fracture criterion. I'm looking at the output and I am not sure I understand the units/output type of the ENRRT (strain energy release rates).

I would expect the output of ENRRT to be in units of [energy per area] but when I plot the ENRRT Abaqus labels it as [energy].

I thought perhaps this could be some integral form of the ENRRT. I did some experiments with an MMB specimen and the results match the analytical solution which is in [J/m^2]. Also when I change the mesh, it still returns the same values.

I think maybe Abaqus labels the axes incorrectly. Can anyone confirm this? Or is there another reason why I'm seeing this?

Thank you for your help, I really appreciate it.
