Seismic evaluation of 3D tunnels in near fault ground motion using domain reduction method
Underground tunnels are an essential part of transportation and utility networks, and their vulnerability to earthquakes has significant socio-economic impacts. Tunnels have suffered substantial damage in past earthquakes, ... -
Computational analysis of polymer nanocomposites across length scales
Polymer nanocomposites (PNC) exhibit excellent mechanical properties making them a promising material for several engineering applications. The enhancement in properties is primarily attributed to the toughening and ... -
Formulations for solving geomechanics stability problems using stress characteristics and finite element limit analysis with power type and Mohr-Coulomb yield criteria
In geotechnical engineering, the stability analysis is often carried out to determine the ultimate collapse load that a geo-structure can possibly withstand. The accurate prediction of the exact collapse load is often very ... -
Fracture and Fatigue Behaviour of Notched Plain Concrete Beams: The Role of Theory of Critical Distances and Acoustic Emission
Concrete structures, including buildings, bridges, pavements, and offshore structures, face a wide range of loading conditions, both static and cyclic. When subjected to fatigue loading, the response of concrete elements ... -
Shear Behaviour of GCL-Sand Interrfaces under Static and Dynamic Conditions
Geosynthetic clay liners (GCL) are unique geocomposites that combine the beneficial properties of bentonite clay and geosynthetics in providing effective hydraulic barriers in landfill systems. In landfills, GCLs form ... -
Bayesian implicit filters for the analysis of numerically stiff structural dynamic state space models
This thesis reports on combined experimental and computational investigations conducted on problems of state and combined state and parameter estimation applied to vibrating engineering structures. The standard dynamic ... -
Improved Methods for Filtration, Drainage and Structural Evaluations With and Without Geocomposites for Subsurface Drainage of Pavements
Pavements are continuously exposed to the environment leading to ingress of water from multiple sources that structurally weakens the pavement materials. The conventional solution for drainage requires granular material ... -
Structural Health Monitoring Accounting for Thermal Variability and Damage using Approximate Bayesian Computation
In structural engineering, damage is characterized as a change in material property, boundary condition, or geometry. The changes in these properties/parameters lead to a change in the measured response. The difference ... -
Parallel methods to solve large-scale stochastic linear and nonlinear mechanics problems in a domain decomposition framework
Parallel methods to solve large-scale stochastic linear and nonlinear mechanics problems in a domain decomposition framework Mechanics problems with inherent uncertainties are mathematically modeled using stochastic partial ... -
A multi-physics-based modelling approach to predict mechanical and thermo-mechanical behaviour of cementitious composite in a multi-scale framework
Concrete is a heterogeneous material whose constituents (e.g., cement paste, aggregate etc.) range from a characteristic length-scale dimension of a nanometre to a metre. Owing to the heterogeneity of concrete and the ... -
Space-Time Gauge Theories for Continuum Modelling of Viscoplasticity, Damage And Electro-Magneto-Mechanical Phenomena in Solids
Over the years, sustained research efforts have aimed to understand the material behaviour under a broad range of response regimes, especially from micromechanical or phenomenological perspectives — via both continuum ... -
Hyperspectral remote sensing for soil property estimation in the context of spectral mixtures
The implementation of sustainable agricultural, hydrological, and environmental management entails an improved understanding of soil properties and its conditions at increasingly finer resolutions. In this context, the ... -
Assessment and Monitoring Of Hydrometeorological Variables And Extreme Conditions for Present and Future Climate Change Scenarios
Monitoring and assessment of Hydrological/hydrometeorological Variables (HVs) like streamflow, soil moisture, precipitation, and temperature are essential for various applications such as prediction/forecasting of natural ... -
Multi-vehicle anticipation-based models for describing driver behaviour in heterogeneous and disorderly traffic conditions
Driver behaviour models are widely used in the traffic engineering literature and practice. They are used for understanding drivers’ manoeuvring decisions in traffic streams. They also form the building blocks of microscopic ... -
A non-classical continuum approach to study the fragmentation of brittle solids
In this thesis, a non-local continuum approach coupled with the phase-field theory and Jones-Wilkins-Lee (JWL) equation of state (EOS) is proposed to model and simulate blast-induced fracture in brittle materials. Also, ... -
Monitoring and Control of Intermittent Water Distribution Network
Millions of people in low and middle-income countries worldwide receive water only for a small fraction of the time in a day through piped networks. Even though the percentage of the world’s population with access to piped ... -
Understanding Catchment Scale Processes: Hydrological Modelling and Information-Theoretic Approaches
Catchments are complex environmental systems, and they serve as the fundamental units for hydrological classification. They are self-organizing systems whose form, drainage network, ground and channel slopes, channel ... -
Approaches to Regional Analysis of Hydro-Meteorological Processes and Extremes
Regional analysis of hydrometeorological variables (e.g., evapotranspiration, precipitation), hydrological processes (e.g., runoff), and their extremes (e.g., drought, floods) is essential for various applications. The ... -
Probabilistic design and optimization of foundations on cohesionless soil using surrogate models
The design of foundations depends on the properties of soil, which are affected by various forms of uncertainties. These uncertainties affect the foundation performance and hence are considered in the deterministic design ... -
Geoelectrical Characterization for Relating Electrical Resistivity and Geotechnical Properties of Soils
This thesis proposes electrical resistivity measurement as a potential method to characterize different types of geomaterials under different environmental conditions. Electrical resistivity method is a promising non-destructive ...
