Structural Health Monitoring Of Composite Helicopter Rotor Blades
(Indian Institute of Science, 2007-04-18)
Helicopter rotor system operates in a highly dynamic and unsteady aerodynamic environment leading to severe vibratory loads on the rotor system. Repeated exposure to these severe loading conditions can induce damage in the ...
Experimental And Numerical Studies On Fatigue Crack Growth Of Single And Interacting Multiple Surface Cracks
(Indian Institute of Science, 2007-05-01)
Design based on damage tolerance concepts has become mandatory in high technology structures. These concepts are also essential for evaluating life extension of aged structures which are in service beyond originally ...
Wavelet Based Spectral Finite Elements For Wave Propagation Analysis In Isotropic, Composite And Nano-Composite Structures
(2009-04-02)
Wave propagation is a common phenomenon in aircraft structures resulting from high velocity transient loadings like bird hit, gust etc. Apart from understanding the behavior of structures under such loading, wave propagation ...
Development And Design Optimization Of Laminated Composite Structures Using Failure Mechanism Based Failure Criterion
(2009-04-27)
In recent years, use of composites is increasing in most fields of engineering such as aerospace, automotive, civil construction, marine, prosthetics, etc., because of its light weight, very high specific strength and ...
Distributed Computation With Communication Delays: Design And Analysis Of Load Distribution Strategies
(Indian Institute of Science, 2005-11-09)
Load distribution problems in distributed computing networks have attracted much attention in the literature. A major objective in these studies is to distribute the processing load so as to minimize the time of processing ...
Multi-agent Consensus Using Generalized Cyclic Pursuit Strategies
(2009-05-11)
One of the main focus of research on multi-agent systems is that of coordination in a group of agents to solve problems that are beyond the capability of a single agent. Each agent in the multi-agent system has limited ...
Shape Optimization Using A Meshless Flow Solver And Modern Optimization Techniques
(2009-03-17)
The development of a shape optimization solver using the existing Computational Fluid
Dynamics (CFD) codes is taken up as topic of research in this thesis. A shape optimizer
was initially developed based on Genetic ...
Numerical Simulations Of Axisymmetric Near Wakes At High Reynolds Numbers
(2009-03-13)
The flow past the needle of a Pelton turbine injector is an axisymmetric wake embedded in a round jet. The wake does not fully relax to yield a uniform velocity jet due to the short distance
between ...
A Neural Network Approach To Rotorcraft Parameter Estimation
(2009-07-03)
The present work focuses on the system identification method of aerodynamic parameter estimation which is used to calculate the stability and control derivatives required for aircraft flight mechanics. A new rotorcraft ...
Rotationally Invariant Kinetic Upwind Method (KUMARI)
(2009-03-11)
In the quest for a high fidelity numerical scheme for CFD it is necessary to satisfy demands on accuracy, conservation, positivity and upwinding. Recently the requirement of rotational invariance has been added to this ...
