compression of cylinder
compression of cylinder
(OP)
Hello,
I have a small problem where I have to compress the cylinder.
For example if I have a cylinder of diametrer 1 cm ,I want to reduce the diameter of the cylinder to 0.5cm.I donot mind even if the length of cylinder increases.
I cannot constraint any face of the cylinder as I want size reduction even at the edges. Can someone recommend a solution to this problem. I am using abaqus to solve this problem.
Thank You.

You can apply pressure to the outside surface of the vessel.

You can fix all nodes in a cross section in the axial direction, then use symmetry to fix a line of nodes lying on a plane in the normal direction. For example:
X-axis parallel to pipe axis - choose any cross section, or one of the ends to apply BC in X
Y-axis intersects pipe at top and bottom - apply BC in Z
Z-axis intersects pipe at sides - apply BC in Y
Or you can use a reference node with a kinematic coupling through a cylindrical csys, leaving radial (DOF 1) free. Or you can use a distributing coupling.
