How to bend a beam to specific radius of curvature

Hollo everyone, 

I got a problem when doing a simulation with a multi-layer beam bending. 

I want to apply the specific radius of curvature to beam such as 0.5mm, 1mm, 5mm and so on. 

But I don't know where I can set up this request. Does anyone can help me?

Many thanks,

You can't specify a specific radius of curvature, but you can apply a remote displacement to the end of the cantilever and set only one rotation, and leave all other DOF free. That will bend the beam into a circular looking shape.

Many thanks to your suggestion. I will try it ASAP. 

Is it possible to use a mandrel to fix the bending radius?

Yes, You can specify a mandrel (rigid body maybe) and define contact and that would control the amount and the position that the beam would bend. If you just want to see a bent shape, I would recommend what peter suggested above.

Thank you Sandeep. Let me test it.
