Effective strain is also called true strain. Phsically, it is represented by the stress over the net area.

Effective plastic strain is related to J2-plasticity. Mathematically, it is equal to Sqrt (2.0*eps(d)*eps(d)/3.0) , where eps(d) is the deviatoric strain.

Effective failure strain is the effecive strain at failure (or peak stress).

I would like to know the difference between Effective Strain, Effective Plastic Strain and Effective Failure Strain.
