Hey There is a difference between both these contacts in capturing the physical behavior correctly.
In the case of Bonded contact, the value of 'Normal force' (that prevents penetration between bodies) and 'Tangential force' (that prevents sliding between bodies) are high.
Whereas in Frictional contact, 'Normal force' could be zero when bodies separate out and the 'Tangential force' is a function of the normal force.
Some of the factors that influence contact forces between two bodies at the interface are:
Material of both bodies.
Shape and topology of both bodies.
Kinematics of interacting bodies.
I suggest you look into Contact Mechanics | Ansys Innovation Courses to understand the behavior and how to set up contacts.
