Definition plastic strain (PE) abaqus 1

[Crowner]

Hi everybody,
Ive been looking for the definition of the plastic strain (PE) output in Abaqus, how is this one computed? In the Users Manual are only informations about normal and logarithmic strain and i can't find anything in the Theory manual either.
Thanks a lot!

Hello,

Do you need Plastic strain formula? if so plastic strain = (Ln(1+ nominal strain))-(Ln(1+(true stress/elastic modulus)))

hope this helps

Hi, Thanks for your help, so abaqus simply calculates the nominal strain through the Deformation Tensor and substracts the elastic strain to get the plastic strain?
Regards

Not only Abaqus, this is the universal formula for plastic strain.
