Modeling and Analysis of Hybrid Renewable Energy for Power Generation
Renewable energy-based power has gained significant global momentum—to minimize fossil-fuel use, combat climate change, and ensure energy security. While renewable energy (RE) is fast-growing, stand-alone single resource-based ...
Liquefaction Resistance and Cyclic Response of Air - Injected Desaturated Clean Sandy Soil: Experimental and Numerical Investigations
Liquefaction has been one of the major concerns in the field of geotechnical earthquake engineering. Various mitigation techniques such as vibroflotation, deep dynamic compaction, explosive compaction, grouting, deep soil ...
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 ...
Reliability Based Design Methods Of Pile Foundations Under Static And Seismic Loads
(2010-09-03)
The properties of natural soil are inherently variable and influence design decisions in geotechnical engineering. Apart from the inherent variability of the soil, the variability may arise due to measurement of soil ...
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 ...
Inter-laminar Stresses In Composite Sandwich Panels Using Variational Asymptotic Method (VAM)
(2013-07-10)
In aerospace applications, use of laminates made of composite materials as face sheets in sandwich panels are on the rise. These composite laminates have low transverse shear and transverse normal moduli compared to the ...
