sheath in compression
(OP)
have a circular plastic sheath that I am compressing at 3 points 120 degrees apart, sheath outer diameter 0.070in, inner diameter 0.040in, trying to figure out how I can calculate the displacement using equations, any bright ideas other than FEA analysis.
regards,

RE: sheath in compression
If howver the sheath is long in the axial direction then you need to solve the plate equation for the same 120 degree arc. That is third year stuff, and may not have a simple solution. In fact with a point load we can be sure it will have infinite deflection.

Yes, a crane hook is a good example.
