What's the difference between nonlinear elastic material and elastic plastic material?

I use the contour integral method to calculate the J-integral in ABAQUS. The constitutive model are deformation plasticity (R-O model) and plastic increment (true stress-strain) respectively. The...

Why is the J-integral of CT specimen calculated by contour integral method in ABAQUS related to the path?

I use the contour integral method in ABAQUS to calculate the J-integral of CT specimen(2D). The material is elastic-plastic, and the constitutive model is established by using incremental...
