Plastic J significance in CTOD equation

I am working on the validation of CTOD.

In the evaluation of CTOD using the
J-integral approach as applied in ASTM E1290 and E1820, the plastic J
component is defined as (Npl*Apl)/(Bn*Bo)
Npl=dimensionless constant(plasticity)
Apl=area under load vs. displacement plot
Bn=ligamen length (W-a)
Bo=section thickness

On E1820 there are different functions provided for Npl if Apl is
evaluated differently (CMOD or load-line displacement).

Elastic-plastic analysis

Hello Everyone,

I am a beginer in using Abaqus. I am going to model a nothed specimen subjected to cyclic loads, to investigate the stress/strain distribution and so on. I would appreciate if you guide me.
