Dear Nothando,

As you mentioned, the simplest way is to define the BC manually by calculating x displacement for given nodes. Alternately, a program can be written which can calculate x displacement (BC) to be applied on each node on the boundary based on its coordinates.

I can think of one more solution. Create a rigid body with the curvature (for given k and its center coordinates). Constrain the rigid body in all directions. Apply load along x-axis on the nodes at the boundary and restrain them to move along vertical direction (if required). Define contact between boundary nodes and the rigid body. This should solve your purpose and still give you the expected results. One need to take care about the amount of force to be applied. If the force is lesser, boundary nodes may not reach the rigid body and in turn may not take the desired curvature. If the force is higher, excess force will transfer to the fixed rigid body without affecting the stress result and yields accurate result.

Thanks Chandrashekhar for your input, I will try it as well.

I found another way: Creating an analytical field using Abaqus CAE then writing out the input file. It actually calculates the displacement for each node.

You could also create a rigid body with the desired geometry and then apply a force to your part to bend it around that body.
