How to get force acting on the interface of tied surfaces?

Hello, now I'm doing simulations using ABAQUS/Explicit. There are two parts and they are tied at adjacent surfaces A and B.

Inertial force and contact force are exerting on one part and I would like to calcuate the interfaial force acting between surfaces A and B, perferablly in components. (longitudianl, circumferential)

Is it possible and how can it be done?  Thank you for your kind advices, in advance.
