Bonds breaking in graphene nanoribbon simulation

Dear all,
I am currently working on the simulation of graphene nanoribbons, and hope to break the bonds when the energy of the atom large enough. The potential file i chose is AIREBO, and i've noticed that this potential allows the bonds to break and form depending on the local geometry. But my question is, how to simulate the physics of breaking of pi bonds? Will it automatically be done by the potential, or should other command lines be implemented?
Thanks so much!
Payton

have you looked at the paper describing the AIREBO potential?
this is where you should find the answer to your questions.

Dear Axel,
Thanks! It is clear now.
