Hey, 

The choice of contact comes down to two main points - one is how close does the simulation represent the actual scenario and the second is how much simulation time and model setup time is involved to get results.

You can start with bonded contacts and check the results. Sometimes bonded contacts might not be the best due to the fact that it might over constrain the parts and lead to spurious stress.

If that is the case you can shift to frictional. Frictional contacts not only make the analysis non linear but also take considerable time while setting up as they are not as simple as modelling bonded contacts.

Thanks
