Software Developing Experience

All the programs (Pre-Processing, Solution and Post-Processing) were developed, complied and executed in UNIX or Windows environment. These programs were written in FORTRAN or C++ Languages.

• Institute of Bioengineering

o In recent years, the Object Oriented Programming is playing a major role in Engineering Analysis. The algorithms developed in recent past for Shell Heat Transfer Elements have reduced the memory and execution time required than conventional Continuum Elements. Successfully added these Shell Heat Transfer Elements to the Element Library and bench marked with ABAQUS.

o Radiation Heat Transfer is a complicated application in Engineering Analysis. It often involves complex differential equations of order 4. Both Surface and Cavity Radiation (which requires complicated Shape Factors or Geometrical Factors) methodologies were prepared.

• Post Doctoral Studies

o Canada – A complete solution program for 3D Turning operation for difficult to cut materials WASPALOY has been developed. It includes Pre-Processing (Iso-parametric Mesh Generation Schemes using 20 Noded Isoparametric Elements), Solution Module and Post Processing (interface module has been developed to analyze in FEMAP and I-DEAS). This project was funded by Pratt & Whitney of Canada.

o Hong Kong – Mathematical Model was proposed based on FEA for Nano-machining of Metal Matrix Composites (MMCs). These results were published in international conference and journals. They very well concur with experimental investigations.

• Ph. D - ‘Themo-mechanical Analysis of Single Edge Cutting using FEM’

Metal cutting is a complicated phenomenon, which involves plasticity. Superficially, the problem may look simple. But, it is one of the complicated manufacturing processes to model mathematically. It is an arduous task to any design engineer in order to estimate the temperatures, stresses and strains developed during machining. The complexity will be manifold when it comes to Machining of Anisotropic Materials (FRPs).

Programs related to heat transfer aspects, a data base to re-evaluate the tool specifications, stress analysis using theory of elasto-plasticity and stress analysis program for machining of FRP's were developed. Above all, these programs were modified to suit 3-D analysis. Stress analysis program runs approximately 10K lines FORTRAN source code.

• M.E - ‘Computer Aided Estimation of Fabrication Cost and Time’

A software has been developed for computing fabrication cost and time for the structures which uses most common welding techniques like manual, semi automatic and automa¬tic welding. This work has been carried out at Welding Research Institute, Bharat Heavy Electricals Limited, Trichy, India. Based on the thesis BHEL released the FACT (FAbrica¬tion Cost and Time) software in commercial circle.
