Multi-linear Disassembly Path Determination: A Geometric Approach
This thesis presents a geometric approach for determining the orientation-preserving disassembly paths of polyhedral
assembly components. Exact disassembly path determination of the components is essential because the ...
Rotational Temperature Measurement in Hypersonic Shock Tunnel using Tunable Diode Laser Absorption Spectroscopy
Atmospheric entry of a spacecraft is considered as one of the critical phases in any planetary mission. Although it lasts only for a few minutes, rapid heating and deceleration can cause severe problems to the spacecraft. ...
A Generalised Modelling of Piezoelectric Composite Shells and Plates using Variational Asymptotic Method
In several fields of engineering, researchers are actively pursuing the possibility to use smart
materials such as piezoelectric composites in order to make the structure smart. Piezoelectric
materials have the capability ...
New Mechanical Methods to Join Sheets in Lap and Butt Configuration and Analytical Model to Predict and Improve Clinching Joint Strength
Mechanical joining of sheets has many advantages over other joining methods in terms of wide variety combination of similar, dissimilar and non-metallic material sheet joining.
In conventional SPR joining, the rivet and ...
Flow and Forces on Rigid and Flexible Plates in Unsteady Rotational Motion
The swimming motion of fishes have long fascinated scientists and engineers. Over
the past few decades, researchers have studied physical models mimicking the tail beat
of fishes in an effort to extract key physical ...
Characterization of a large scale hypersonic shock tunnel and investigation of the effect of roughness on a large cone boundary layer flow
High speed flight is ridden with engineering challenges, some of which have been studied
for decades with only minor improvements. Boundary layer transition to turbulence in
highMach number flow is one such topic, which, ...
Propulsive Performance of Pitching Foils Investigated with Viscous Vortex Particle Method
Unsteady flapping foil based thrusters have emerged as ideal candidates for enabling propulsion in bioinspired
and bio-mimetic devices such as autonomous underwater vehicles. To a large extent, this
emergence has been ...
Flame Particle Tracking Analysis of Turbulence-Premixed Flame Interaction
This work describes the computational and theoretical developments made in the understanding of turbulence-premixed flame interaction, using both lean and rich H2-air mixtures, in a flow field of near-isotropic turbulence. ...
Experimental and Numerical Studies to Strengthen the Adhesive Bonded Single Lap Joint
In this work, an attempt has been made to strengthen the adhesive bonding using various concepts like hybrid joints, dual and mixed adhesive bonded joints. One of the most commonly occurrence of defect in adhesive bonded ...
Characterization of high enthalpy flows in the IISc free-piston driven shock tunnel using Two-Colour Ratio Pyrometry
High temperature and its associated effects set the hypersonic flow regime apart from other class of flows. Viscous dissipation raises the internal energy of the high-kinetic-energy gas as it slows down in the boundary ...
