Prof. Stephen Tsai, Department of Aeronautics and Astronautics, Stanford. Dear Prof. Tsai, I am a final year student of the four-year Bachelor of Technology program in Aerospace Engineering at the Indian Institute of Technology, Bombay, India. I have secured admission to the M.S. program, and would like to take this opportunity to enquire about my working under you. I have been informed that due to the very low number of fellowships available to the Department, I won't be funded by the department for the first year of my studies at Stanford. Since I have no sources of outside funding, it would be extremely difficult for me to pursue my studies at Stanford. I would like to be considered for any openings that might exist in your research group, or for a teaching assistantship. I understand from the Stanford home page that your research interests lie in the mechanics of failure of composite materials. I was exposed to Composite Materials in my 4th year and I have since retained an active interest in it. As part of my final year project, I have developed a model for the elastic and strength properties, based on a volume averaging method. I would be extremely grateful to you if you would advise me on my chances of working under you in composites. I would also be interested in working in any other related area. I realize that obtaining an assistantship would require me to devote time towards research at a time when I should be concentrating on building up my knowledge of the fundamentals. I have performed well in my courses, while being involved in research projects simultaneously. In my seventh semester, I successfully developed a model for the elastic properties of 3D Woven Fabric Composites, under the guidance of Dr. N.K. Naik, while at the same time performing well enough in six full-time courses to maintain my position at the top of the class. I am currently working on the strength prediction of 3D Composites. I have also had opportunities to work in research groups at other leading establishments in India, which I have included in my resume attached to this letter. I am eager to be able to work under you, and I am confident that, given an opportunity, I will fulfill all expectations made of me. I hope that you will be able to offer me an assistantship to enable me to pursue my studies at Stanford. Thanking you for going through this mail amidst your busy schedule and eagerly awaiting a favorable reply, Yours sincerely, T.

In my final year project under Prof. N.K. Naik, I have developed a model for the analysis of 3D ortogonal weave fiber composites, based on a volume averaging method, for predicting the elastic and strength properties. It is based on a isostress distribution at the macro-level, and an isostrain distribution at the micro-level. The unit cell is discretized into a very large number of cuboidal elements and the load flow into each is calculated for a multi-directional on- axis loading case. The failure of each element is determined using a quadratic failure criterion. I am currently developing a model for the thermal properties of the 3D composite. I also propose to apply formal optimization techniques for optimal design, within the framework of the analytical model. Of particular interest is the tailoring of the weave geometry for maximum stiffness and strength properties. ## B.Tech Seminar : SYSTEM IDENTIFICATION TECHNIQUES IN STRUCTURAL PROBLEMS. In my credit seminar under Prof. A. Joshi, I studied various techniques used for structural identification. Emphasis was laid on a comparative study of different commonly used techniques with an eye on their comparative merits and demerits. This seminar involved a extensive literature survey and culminated in a presentation at the department before students and faculty. I also presented a compiled report on the literature survey. ## Project : SEA LEVEL PREDICTION USING ARTIFICIAL NEURAL NETWORKS. As part of my summer training at the CSIR Centre for Mathematical Modeling and Computer Simulation under Dr. R.N. Singh, I developed a feedforward neural network model for Time-Series Prediction of the Sea Level variation. This involved the training and testing of a neural network using sea level data from different stations over a period of the last 50 years. ## Flutter and Divergence Analysis of Large Aspect Ratio tapered Wings Developed modules in MATLAB for flutter and divergence eigen value analysis as a part of the course on `Introduction to Aeroelasticity'. The course project also involved a parametric study of the effects of Aspect ratio and Taper ratio on the eigen values. ## Aerodynamic Analysis of 2-D surfaces This project involved the development of a software for aerodynamic analysis of 2-D lifting surfaces using First Order Panel Methods. The software was developed in C and was applied to study flow over a finite twisted rectangular wing. ## Experimental study of Free Jets and Boundary Layers. This study was carried out in the Experimental Aerodynamics Division, National Aerospace Laboratories. In this study under the guidance of Dr. S. Sundaram, I carried out a study on the growth of the boundary layer in the Boundary layer tunnel. I also carried out a study on free jets and also estimated the aerodynamic coefficients of the Polar Satellite Launch Vehicle (PSLV) model via test runs in a 0.6m Transonic Wind tunnel. *=====================COMPUTER PROFICIENCY=================================* Operating Systems : Unix, DOS, Linux, Windows, NOS/VE Mainframe Platforms : DEC, SUN, Macintosh, PC586, PC486 Languages : C, C++, Fortran77 Software : Matlab, AUTOCAD ************************************************************************* From tbj@skypak.aero.iitb.ernet.in Tue Apr 1 02:48:57 1997 Date: Tue, 1 Apr 1997 02:48:56 +0530 (IST) From: "T.

This seminar involved a extensive literature survey and culminated in a presentation at the department before students and faculty. I also presented a compiled report on the literature survey. ## Project : SEA LEVEL PREDICTION USING ARTIFICIAL NEURAL NETWORKS. As part of my summer training at the CSIR Centre for Mathematical Modeling and Computer Simulation under Dr. R.N. Singh, I developed a feedforward neural network model for Time-Series Prediction of the Sea Level variation. This involved the training and testing of a neural network using sea level data from different stations over a period of the last 50 years. ## Flutter and Divergence Analysis of Large Aspect Ratio tapered Wings Developed modules in MATLAB for flutter and divergence eigen value analysis as a part of the course on `Introduction to Aeroelasticity'. The course project also involved a parametric study of the effects of Aspect ratio and Taper ratio on the eigen values. ## Aerodynamic Analysis of 2-D surfaces This project involved the development of a software for aerodynamic analysis of 2-D lifting surfaces using First Order Panel Methods. The software was developed in C and was applied to study flow over a finite twisted rectangular wing. ## Experimental study of Free Jets and Boundary Layers. This study was carried out in the Experimental Aerodynamics Division, National Aerospace Laboratories. In this study under the guidance of Dr. S. Sundaram, I carried out a study on the growth of the boundary layer in the Boundary layer tunnel. I also carried out a study on free jets and also estimated the aerodynamic coefficients of the Polar Satellite Launch Vehicle (PSLV) model via test runs in a 0.6m Transonic Wind tunnel. ************************************************************************* From tbj@skypak.aero.iitb.ernet.in Tue Apr 1 23:55:33 1997 Date: Tue, 1 Apr 1997 23:55:33 +0530 (IST) From: "T.

In my final year project under Prof. N.K. Naik, I have developed a model for the analysis of 3D ortogonal weave fiber composites, based on a volume averaging method, for predicting the elastic and strength properties. It is based on a isostress distribution at the macro-level, and an isostrain distribution at the micro-level. The unit cell is discretized into a very large number of cuboidal elements and the load flow into each is calculated for a multi-directional on- axis loading case. The failure of each element is determined using a quadratic failure criterion. I am currently developing a model for the thermal properties of the 3D composite. I also propose to apply formal optimization techniques for optimal design, within the framework of the analytical model. Of particular interest is the tailoring of the weave geometry for maximum stiffness and strength properties. ## B.Tech Seminar : SYSTEM IDENTIFICATION TECHNIQUES IN STRUCTURAL PROBLEMS.

This involved the training and testing of a neural network using sea level data from different stations over a period of the last 50 years. ## Flutter and Divergence Analysis of Large Aspect Ratio tapered Wings Developed modules in MATLAB for flutter and divergence eigen value analysis as a part of the course on `Introduction to Aeroelasticity'. The course project also involved a parametric study of the effects of Aspect ratio and Taper ratio on the eigen values. ## Aerodynamic Analysis of 2-D surfaces This project involved the development of a software for aerodynamic analysis of 2-D lifting surfaces using First Order Panel Methods. The software was developed in C and was applied to study flow over a finite twisted rectangular wing. ## Experimental study of Free Jets and Boundary Layers. This study was carried out in the Experimental Aerodynamics Division, National Aerospace Laboratories. In this study under the guidance of Dr. S. Sundaram, I carried out a study on the growth of the boundary layer in the Boundary layer tunnel. I also carried out a study on free jets and also estimated the aerodynamic coefficients of the Polar Satellite Launch Vehicle (PSLV) model via test runs in a 0.6m Transonic Wind tunnel. *****************************************************************
