Hi everybody

I have got problem which I want to press fit the Hip implant to Femur bone and then do the FEA, anybody has got any idea to do this modeling ? I have got Femur and Implant separately, also I know How do FEA and I have got all forces and properties of material.

All I need, How put Implant to femur with similar to real operation (Press fit) condition and apply friction between two surfaces (Hip surface and Femur Bone surface) due to FEA.

Really thanks

Mahdi

Model each at their actual size with the overlap included
begin a static study
remove default contact set
create a new contact set, type: shrink fit
Apply loads and restraints (I found it requires at least one load)
Solve

I have also heard of a method where a temperature study was done to create the same effect. Never tried it myself.
