thank you for the note. Yes, we should include a description in the manual of these new features. In the meantime, here is the explanation.
The CF_damage is a parameter indicating how much the element response deviate from the elastic one.
Damage status shows how the element forces relate to the ultimate capacities:
SD - total shear capacity exhausted, full shear failure
FD - total flexural capacity exhousted, full flexural failure
MV - both moment and shear ultimate forces are reached, plastic behaviour in flexure and shear
M - moment capacity reached, plastic behaviour in bending/flexure
V - shear capacity reached, plastic behaviour in shear
I hope my explanation helps.
With best regards
