Using a radial coordinate system, apply a uniform displacement to nodes on the periphery of the part. This is basic stuff; you should read about this in the documentation.

Hi IceBreakerSours, thanks for the help. I did so and in the next step of my analysis, I wish to fix the periphery in all translational degree of freedom but was prompt with an error saying some nodes have displacement constraints simultaneously when the job is submitted. What should I do to rectify this error?
When applying displacements/constraints to your periphery node set did you specify two different coordinate systems (cylindrical/global)? ABAQUS doesn't like that, and will give you an error like the one you described.
Thank you so much for replying. My modeling involves two steps. In step one, I prestretched the part by applying uniform displacement on the periphery nodes in radial direction. In step 2, I wish to fix the prestretched periphery nodes (in all translational degree of freedom) and apply a pressure on it. I propagated step 1 to step 2 and specified the same cylindrical coordinates in both steps but was prompt with the error.
There are ways to do this directly in the input deck but I suspect you are beginner so I suggest the following: Check the Boundary condition manager and simply propagate the displacement BCs to the next step. And, in the load manager, apply a pressure in step 2 on the surface of interest.

Create a boundary condition for the periphery of the disk. With a cylindrical coordinate system apply the radial displacement and restrain the remaining 5 DOFs. In the second step apply a pressure load.
