Modeliing a thin-walled cylinder
Modeliing a thin-walled cylinder
(OP)
I am trying to model a cylinder (1mm thick, 16mm dia, 5mm height) of stainless steel. The cylinder has cuts made in its wall with the intention of making it flexible in pure compression. What kind of elements would be good such an analysis?

RE: Modeliing a thin-walled cylinder
If you are worried about the stresses in the vicinity of the cuts, you might want to use solid (brick) elements.
If the compression direction is parallel to the axis of the cylinder and the cuts in the wall are designed to make the cylinder compliant along this axis, you may want to consider performing a buckling analysis if the remaining "beams" are loaded in pure compression.
Alternately, if you need compliance along the axial direction, you might want to design the cuts so that the remaining beams are loaded in shear or bending.
