One way to smooth the contact pressure distribution is to change the default normal stiffness. 

Change Normal Stiffness to Factor and use a value of 0.1 or 0.01 instead of the default value of 1.0 and change Update Stiffness to Every Iteration.

Another thing you can do is use a finer mesh in the contact region. This is easily done using a Contact Mesh Sizing control.

Take the free course on Contact Mechanics.
