Failure Analysis of Hip Prosthesis:
The research deals with the implementation of alternative
material for the human hip joint. Total hip replacement is taking a new
dimension with the UHMWPE (Ultrahigh molecular weight polyethylene), Ti6Al4V,
Co-Cr alloy and PEEK (PolyEtherEtherkeetone) composite materials. Using the
material properties of these materials an idealised hip prostheses model has
been developed and analysed in ANSYS
using a 3D-Finite Element Analysis. Static and Dynamic Stress
Analyses were done on the model and the results were compared with the
previous standard results of Bergmann’s model and Kayabasi model. The fatigue analysis has been done
on the model for different activities also to determine the life period of the
prosthesis using MATLAB. A strength degradation model is taken for this fatigue
analysis.
Stress values and fatigue life were found for different
postures like slow walking, normal walking, fast walking, upstairs climbing,
downstairs, standing up, sitting down, standing on 2-1-2 legs and knee bend. Further work has been done on Wear Modelling of the Prosthesis
based on contact analysis on this research. Statistical methods are used
to determine the wear rate of the model.
A new empirical relationship has been used to find the wear rate of
prosthesis material by modifying the Archard’s wear law. This method helps in
analysing the damage on the model. A collective
work of stress (static and dynamic) analysis, fatigue analysis, contact and
wear analysis have been performed to give the suggestion to the medical
surgeons to use which model of prosthesis and what material can be used for
which aged patients.
Course work opted for are Advanced Engineering
Mathematics, Theory of Elasticity,
Finite Element Analysis and Introduction
to Composite Materials. Have done a
review on knee and hip joints for the comprehensive examination as a part of
course works. In addition to these, a static
analysis on knee joints using Ansys was also been done, loads with different
materials were applied to the joint and the stress values also were obtained and
applied them in the fatigue analysis using MATLAB and got the fatigue life of
that knee prosthesis.

Finite Element Analysis of Engine
Flywheel for Ashok Leyland, a leading OEM - The project deals with an Axi-Symmetric Model of
Flywheel. Stress analysis is done on the flywheel using I-DEAS (Master Series)
software. The dimensions were modified and the stress values were reduced from
the existing model. The rotation speed of the flywheel was set at about 3500
rpm and this project is a big success under Indian road conditions.
