In abaqus, in order to analyse the plastic dissipation at the end of a crack, do I need to specify the plastic behaviour of my material?

I would so yes, and in terms of plastic behavior of the aluminium beam I'm not 100% sure how to do this.

Shalin P Marathe

While defining the material properties you can define the rate dependent data in abaqus where you can define the plastic behavior of the material whether material follows power law or kinematic hardening etc.

Ajay Kumar

yes it is necessary to specify the plastic material behavior properties as well as you have to do the non-linear analysis.
