Studies on Glass Fiber-Reinforced Composites for CAE-Driven Design of Impact Safety Countermeasures
(2018-01-29)
Man-made materials such as fiber-reinforced composites (FRCs) can be tailored for optimum performance in product design applications in terms of strength and weight. The current work is aimed at studying the behaviors of ...
Prediction of Physical Behavior of Rotating Blades under Tip-Rub Impact using Numerical Modeling
(2018-02-09)
Rotating blades, which are the most critical components of any turbo-machinery, need to be designed to withstand forced vibrations due to accidental tip rub impact against inner surface of casing. These vibrations are ...
Pragmatic Design of Compliant Mechanisms using Selection Maps
(2018-04-02)
A pragmatic method for designing compliant mechanisms is developed in this thesis, by selecting among existing mechanisms one that may be modified as required. This method complements existing techniques by answering ...
Static Balancing of Rigid-Body Linkages and Compliant Mechanisms
(2018-03-07)
Static balance is the reduction or elimination of the actuating effort in quasi-static motion of a mechanical system by adding non-dissipative force interactions to the system. In recent years, there is increasing recognition ...
Design and Development of Capacitive Micromachined Ultrasonic Transducers
(2018-02-22)
This thesis presents the design and analysis for development of a Capacitive Micromachined Ultrasonic Transducer (CMUT), a novel sensor and actuator, aimed at replacing the conventional piezoelectric transducers for ...
Experimental Studies on Extremely Small Scale Vibrations of Micro-Scale Mechanical and Biological Structures
(2018-05-14)
Experimental vibration analysis of mechanical structures is a well established field.Plenty of literature exists on macro scale structures in the fields of civil, mechanical and aerospace engineering, but the study of ...
Optimal Synthesis of Adjustable Four-Link Planar and Spherical Crank-Rocker Type Mechanisms for Approximate Multi-Path Generation
(2018-04-02)
The well known synthesis problem of obtaining dimensions of a four-link mechanism such that a point on the coupler link traces a desired path has been extensively studied. There are two types of path generation–path specified ...
Experimental and Numerical Studies on Phase Shifting in an Inertance Pulse Tube Cryocooler
(2018-06-21)
This work is concerned with the design, development and performance evaluation of an inertance Pulse Tube Cryocooler (PTC). The main components of a PTC are the compressor, regenerator, pulse tube and inertance tube coupled ...
Effect of Semi-Solid Processing on Microstructural Evolution and Mechanical Behavior of Austenitic Stainless Steel
(2018-06-19)
In view of the significant advantages offered by semi-solid processing, such as reduction in number of intermediate processing steps and energy input, and the potential for improving component complexity, it is of paramount ...
Piezoelectric Micromachined Ultrasound Transducers : From Design to Applications
(2018-06-21)
Ultrasonic sensors are well known for various applications such as NDT, ultrasound imaging, and proximity sensing. Conventional ultrasound transducers are bulky, work at notoriously high voltages, and consume significant ...
