State and Parameter Estimation in Water Distribution Systems
Water Distribution Systems (WDS) are one of the most important infrastructures in a society, which has a direct impact on human lives. Water authorities around the world are expected to supply the required amount of water ... -
Experimental Investigations Into Fracture and Fatigue Behavior Of Plain and Reinforced Concrete Beams Using Acoustic Emission Technique
Concrete is the most widely used material in the world for construction of infrastructures and there are quite a few gaps in understanding its behaviour under different loads. Fracture in concrete occurs at pre-existing ... -
Development of an efficient domain decomposition algorithm for solving large stochastic mechanics problems
With the growth of computational resources available, demand on the accuracy and speed of simulation is steeply increasing. Accordingly, accounting for the variabilities in the simulations plays a pivotal role in taking ... -
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 ... -
Adaptive reduced order modeling of dynamical systems through novel a posteriori error estimators : Application to uncertainty quantification
Multi-query problems such as uncertainty quantification, optimization of a dynamical system require solving a governing differential equation at multiple parameter values. Therefore, for large systems, the computational ... -
Two-temperature thermodynamics and continuum modelling of viscoplaticity in metals
In recent years, numerous studies have shown the complexity of plastic deformation in metals. The accuracy in modelling inelastic behaviour holds great significance for engineers as metals and metallic alloys are extensively ... -
At-site and Multisite Probabilistic Forecasting of Streamflow
Streamflow forecasts are very useful for a variety of applications such as flood warning, reservoir operation and water resources planning and management, especially in countries like India where streamflow can be highly ... -
A Study on Isogeometric Analysis of Laminated Composite Beams
A myriad of physical processes in engineering and other science branches is represented using differential equations with boundary conditions. Finding the exact solution for the differential equation is quite challenging ... -
Evaluating Climate Change Mitigation & Adaptation Potential of Sustainable Urban Transport Measures in India
The global climate is transforming due to increased GHG emissions. Globally, the response to climate change has been through mitigation to reduce greenhouse gas emissions. Urban transportation is the second leading source ... -
On a Few Non-Classical Perspectives in Solid Mechanics
Postulates in solid mechanics can be broadly classified into three groups describing the geometry of a configuration, mechanical equilibrium and thermodynamics of the deformation process. The geometry defined on a configuration ... -
Role of Physico-chemical Processes And Micro-structural Features in Influencing Moisture Loss and Engineering Properties Of Compacted Residual Soils Exposed To Environmental Relative Humidity
The moisture content of residual soils above the water table, and near ground surface (≤ 6 m) is influenced by the environmental relative humidity (RH). The focus of this thesis is to examine the physico-chemical and ... -
Micromechanical modeling of fracture and fatigue behavior of cementitious composites
The ubiquitous use of concrete as a construction material in the civil engineering industry demands a thorough understanding of its failure process under different types of loading. The composite nature of cementitious ... -
Response of Plain and Reinforced Concrete Elements to Various Mechanical Loads
Reinforced concrete (RC) is being used for a wide range of structural applications. In order to design safe and economical RC structural elements it is necessary to analyse these elements accounting for the realistic ... -
Methodologies for Risk Assessment of Landslides Induced by Rainfall and Earthquake
Landslide is one of the greatest natural catastrophes and poses a major threat to lives and property worldwide. As development expands into unstable hill areas under the pressure of increasing population and urbanisation, ... -
Analysis of Laterally Loaded Piles in Clayey Soils with Sloping Ground
In the present study, a small scale 1-g model test has been developed in the laboratory to study the behaviour of a long flexible single pile embedded in a slope of soft clay with different slope angles and L/D ratios, and ... -
Non-classical continuum models for solids using peridynamics and gauge theory
This thesis focuses on three areas of nonclassical continuum mechanics of solids. In the first part, we develop a few peridynamics (PD) models and solution strategies for discretized PD equations in the context of the ... -
Studies on alkali activated compressed earth bricks for structural masonry
Earth based construction materials are acknowledged as low carbon and low embodied energy materials. The investigations dealt in the thesis were mainly focused on exploring the geopolymer and lime-ground slag binders for ... -
Studies on the Mechanisms of Fracture, Evolution of Microcracks and Size Effect in Concrete through Acoustic Emission Analysis
The mechanics of fracture evolution in heterogeneous material like concrete is a distinct and complex phenomenon and still stands as an open problem after decades of research. A cluster of multi-scale cracks ahead of the ... -
