Non-classical mechanics and thermodynamics for continuum modelling of solids
This thesis dwells upon several aspects of continuum mechanics and thermodynamics to model elastic and inelastic response of solids. Broadly, the work presented may be categorized into two parts{ one focusing on the ...
Semi-active Control of Earthquake Induced Vibrations in Building Structures using MR Dampers: Algorithm Development and Benchmark Application
The thrust of this thesis is the development of two different kinds of feed-forward control strategy using the semi-active device MR damper to monitor MR damper supply current/voltage. The study develops a feed-forward ...
Strain-rate Dependence of Rock Joint Strength and Related Stability of Slopes and Tunnels
Understanding the strain rate-dependent strength behavior of rock joints is important since displacement rates along rock joints in field can exceed the suggested displacement rates (0.02 mm/min-0.5 mm/min) for laboratory ...
Experimental and numerical studies on Mode-I ductile fracture behaviour of Magnesium
In recent years, weight reduction of automobiles is being achieved by using light weight metals like magnesium (Mg) in the form of cast or wrought products. However, the structural application of Mg and its alloys is limited ...
Estimation and Control of Friction in Bulk Plastic Deformation Process
Friction plays a significant role in bulk plastic deformation processes in controlling the tool life, formability of the work piece material and the quality of the finished product such as, surface finish, microstructure ...
Seismic response of Geocell Retaining walls
Use of tensile reinforcement for improving the seismic stability of retaining walls has gained considerable attention in recent times and has become a very common practice. Compared to planar geosynthetic materials, geocells ...
Liquid bridge breakup and detachment dynamics investigated using dynamic domain multiphase flow simulations
Liquid bridges, formed between two solid surfaces in close proximity are encountered in a variety of engineering and daily life applications. The dynamics of a liquid bridge including its evolution that typically involves ...
Constrained Optimal Guidance Design of Interceptors for High-Speed Ballistic Targets
In this thesis, optimal control theory has been applied to design constrained terminal guidance algorithms for interceptor to destroy incoming high speed ballistic targets. There exist several optimal guidance algorithms ...
Behaviour of Granular Materials Under Shock and Blast Loading - A Shock Tube Investigation
Granular and porous materials based protective layers have proven to be very good shock absorbing medium. Although sand material is widely used (as sand bags) till date in civil and military applications as a blast mitigating ...
Mapping the Transient Morphologies and Demixing Behavior of Polystyrene/ Poly(vinyl methyl ether) Blend in the Presence of Multiwall Carbon Nanotubes
Multiphasic materials with precise structures are essential in designing materials for applications in various diverse areas like sensors, photovoltaics, porous membranes, etc. The transient morphology developed during ...
