Forces In Abaqus

The only way to relate <...torque...> to <...pressure...> is to introduce something with the dimensions of [length]^cubed. There isn't enough in the original post to determine what it is. In its absence, nobody <...can...>.

I am trying to evaluate the contact pressure on the sleeve of a roller chain. There was a pre-tension of 20Nm acting on the chain pin and sleeve on either side.In which form of load do you suggest me to apply this tension in Abaqus ?

How about a drawing?

WHY do you want to apply torque to a shell surface?

Simulation of logrolling?

I just couldn't picture it. He didn't define the shell surface, so I think I immediately thought "complex". Your reply is apt to the topic, and OPs thread in the interrim bears this out. Hmh.

I just picked the first thing that came to mind about applying torque to a cylinder.

The roller chain instance may be complex. In the straight shots between sprockets, there is no torque on the sleeves. However, as the chain goes around any sprockets, the forces vary in ways that are complicated by chain wear ("stretch") and by the sleeve/pin versus sleeve/sprocket coefficients of friction as well as by lubrication.

Exactly. At first, i am trying to apply the pre-tension to the pin surface pressfitted by link plates. And then the bushing tension derived from mks to the pin surface surrounded by bearing sleeve.

...and the reason for not mentioning this stuff in the original post was what, please?

There was no reason, I think I didn't elaborate the question to the point. But now, I think you understood the scenario. If you do have suggestions, it would help me tackle the challenge.
