Pulley-belt simulation with slip ring connector

[Xabi33]

I am trying to simulate a pulley-belt transmission in Abaqus.

I am quite lost though at how to make the belt behave as a traction belt and not as an isotropic solid. I've read that the Slip Ring connector is used for such applications, but I am unsure at how to use it in my 3D solid belt. I would appreciate if someone shared a little tutorial of how to approach these problems or gave me some hints on the matter.

Thanks in advance

 

[FEA way]

It should work even without the use of connectors, just assign proper material properties to the belt (hyperelastic material model will best represent its behavior).
