Static And Dynamic Fea Analysis Of Acetabular Cup-Ashish Sharma
1. Static & Dynamic Behaviour of Acetabular cup using finite element analysis
2.
3. Forces applied to the prosthesis due to human activity generate dynamic stresses varying in time and resulting in the mechanical fatigue failure of implant material.

14. ELEMENT TYPE: SOLID45 MESH: Volume mesh with the smart size 7 BOUNDARY CONDITIONS: applied on the upper surface of the cup LOADING : Calculated pressure on the inner surface of the cup
23. Conclusion: In this project we have identified loosening as the most common failure aspect of acetabular cups and high stiffness figured out as the most contributed aspect to it, so by FEA we can finally figure out which material would be better to design our prosthesis so that it wont fail to withstand higher stresses.
