Satellite Attitude Determination from Terrestrial/Planetary Landmarks
Attitude Determination (AD) or specifying orientation relative to a known reference frame
plays a crucial role in meeting the mission specific pointing goals of a satellite. Attitude sensors
provide measurements of known ...
Permeability Modeling for Single Scale and Dual Scale Fabrics and its implementation to Fabrics Undergoing Shear
Composites have found applications, right from high-end aerospace structures to naval and land-based structures. These structures are realized by manufacturing processes like, autoclave and vacuum assisted resin transfer ...
Uncertainty modeling and analysis of aerospace structures
Aerospace structures are different from other structures due to the difference in the required
properties for an aerospace application. The primary motivation of this kind of structure lies in
its lightweight nature, ...
Blast Mitigation Strategies for Marine Sandwich Structures
Blast mitigation is being researched from the time of world war II. There were full field blast tests and analytical studies on the performance of monolithic structures to mitigate blast load. Sandwich structures were also ...
Wave Propagation in Adhesively Bonded Single Lap Joints: Solution of Forward and Inverse Problems
The use of adhesives for bonding composites as well as metals is rapidly increasing since it provides uniform load transfer and is free of stress concentration seen around the drilled holes in bolted or riveted joints. ...
Optimization of a higher-order sandwich composite beam under uncertainties
Optimization under uncertainties of structures is a challenging field due to the requirements of high computational resources. The typical approaches include reliability-based design optimization (RBDO) and robust design ...
Aerodynamics of Nose Mounted Propeller Aircraft
The thesis deals with the aerodynamic analysis of a nose-mounted propeller aircraft using the flow solver HiFUN. Unsteady RANS simulations using sliding mesh technology is performed on aircraft with the propeller. The study ...
Asymptotically Correct Dimensional Reduction of Nonlinear Material Models
(2018-07-30)
This work aims at dimensional reduction of nonlinear material models in an asymptotically accurate manner. The three-dimensional(3-D) nonlinear material models considered include isotropic, orthotropic and dielectric ...
Effect Of Cross-sectional Nonlinearities On Anisotropic Strip-based Mechanisms
(2013-05-28)
The goal of this work is to develop and demonstrate a comprehensive analysis of single and multi-body composite strip-beam systems using an asymptotically-correct geometrically nonlinear theory. The comprehensiveness ...
Design and Analysis of Multifunctional Composites for Unmanned Aerial Vehicles
The principal aim of this thesis is to analyse the effectiveness of multifunctional composites as intelligent structures to improve mechanical properties and activate additional non-structural features. In order to investigate ...
