Abaqus Low cycle fatigue - Hysteresis Energy Criteria

Hi,

I am trying to do Low cycle fatigue analysis in abaqus, and

according to the Documentation, for bulk material damage initiation and damage

evolution definition, I can use the criteria (and type for Damage evolution) as

"Hysteresis Energy". And have to define 4 material variables C1 to

C4.

But in the abaqus material library (in abaqus-CAE) i could find

all the other criteria but not the "Hysteresis energy". I also tried

to define it in the *.inp file but abaqus could not read it (apparently wasn't

writing it correctly).

So please anyone can help me to define this material property. Help either with material library menu

or with the *.inp file format, will be appreciated
