FATIGUE LIFE OF NOTCHED ALUMINUM BEAMS AT ELEVATED STRESS LEVELS
In this thesis, Fatigue life of beams subjected to various levels of vibration is studied experimentally and theoretically. Accelerated testing involves testing at levels higher than the normal usage level in order to reduce testing time and is of great interest to automotive and other types of industry where components are subject to vibration. Accelerated testing criteria are explored by correlating theoretical predictions with experimental results and the variation of fatigue life with the damping ratio was studied for different theories.

Design of Pyrobolt Actuated Stage Separation System Pro-E:
The pyrobolt actuated stage separation mechanism is low shock stage separation mechanism. The key of this mechanism is ‘Pyrobolt’, which is designed in Pro-E. This project involves various component drawings, modeling and assembling of the stage separation mechanism for the rocket motors was performed in Pro-E and AutoCAD.

Modeling of Spin Recovery System in Pro-E:
The above project involved extensive parametric part modeling, assembly modeling, pipe routings of missile systems, consisting of about 400 components. This results in better-informed design decisions and to resolve all design issues before the first physical prototype, resulting in huge saving in time and resources. All production drawings are automatically generated from the solid model.

Modal Analysis of Muffler and Cylinder:
Designed ‘Muffler’ and ‘Filter’ in Pro-E and the theoretical and experimental modal analysis of Muffler and Filter were performed and the results were compared to know the behavior of the parts in real world scenario. ANSYS was used for the theoretical modal analysis calculation and the experimental results were obtained with the help of PULSE analyzer and MESCOPE software. Impact and shaker tests were performed to determine the accuracy of the mode shapes.

Modal Analysis of Aluminum Cylinder:
Modal analysis of an aluminum cylinder was performed to calculate the natural frequencies and mode shapes theoretically and verified them with the experimental values obtained by the Impact hammer test and Shaker tests with the free-free type of boundary conditions.

Three-Dimensional Modal Analysis of a Complex filter:
Modeled ‘Filter’ in Pro-E and performed modal analysis of the filter with the help of the PULSE analyzer using Impact hammer test and Shaker test. The results were exported to ME scope for finding out the damping and to animate the 3D mode shapes.

Design and Analysis of Aircraft wing:
Aircraft wing is modeled in Pro/E, Static and Modal analysis is performed using Ansys. Experimental modal analysis of the prototype aircraft wing is performed by using Pulse analyzer and MESCOPE software. The stresses induced are studied, and the aircraft wing is redesigned by modifying its geometry in order to eliminate the stress concentration areas.

Truss Design Using Pro/E:
Modeled and assembled a triangular truss element in Pro/E. The assembly and individual truss component part files had all dimensions assigned to a single layout. A truss analysis of force distribution in individual elements was done manually and the corresponding equations were input as relations in the layout. The program then calculated the part dimensions after the user supplied the material properties and Factor of safety parameters. The calculated dimensions could then be updated automatically in all the part and assembly files.

Design of Function Generator:
A layout for the synthesis of a four-bar function generator based on freudenstein equations is developed in Pro/E such that the program calculates the required lengths of the coupler and follower for any given length of the crank, input and output angles.

Motion Analysis of a Slider- Crank Mechanism:
Slider-Crank mechanism is modeled in Pro/E and motion analysis is performed in Pro/Motion. Determined force and torque produced in the joints and analyzed using Pro/Mechanica.
