Second order work

[Cansand]

Hi
Is there any way where I can creat a field variable representing the second order work ( dsij.deij )
dsij is the incremental stress tensor and deij is incremental strain tensor
Thanks

No. Maybe a state variable.

Xerf what do you mean "Maybe a state variable"

Field variables are associated with nodes.
State variables are associated with integration points.
The material stiffness matrix is computed at each integration point.
