Monte Carlo Simulations With Novel Sampling Variance Reduction Schemes For Structural Reliability Estimation
The work reported in this thesis is in the area of computational structural reliability modelling. The primary focus of the study is on the estimation of structural reliability using Monte Carlo simulations with sampling ... -
Numerical Modeling of Sediment Transport using ANUGA Sed: Application to Mahanadi River Basin, India
Soil erosion and sediment transport are natural processes primarily driven by water. However, excessive human interference through agriculture, urbanization, and the construction of water storage reservoirs has significantly ... -
Non-intrusive reduced order modeling of dynamical systems with large stochastic dimensions
The work done in this thesis falls under the broad category of computational mechanics. This thesis addresses the computational challenge of high-dimensional regression and interpolation within the framework of a proper ... -
Analysis, Modelling, and Optimization of Gate-To-Gate Aircraft Operation for Enhanced Air Traffic Management
The global air passenger demand will surpass the 10 billion mark by the end of 2040. India itself is poised to become the third largest aviation market and traffic generator by 2033, with a forecast of over 950 million ... -
Developing Decision Support for Electric Vehicle (EV) Adoption & Charging Infrastructure Planning
Majorly reliant on petroleum products, the transportation sector accounts for 25% of the global energy demand and 23% of carbon dioxide emissions. Among all the modes of transportation, road vehicles are the primary sources ... -
Modelling Multimodal Mode Choice Behaviour with Spatial Variability in Level of Service Attributes
Cities worldwide are grappling with declining public transit usage, primarily due to insufficient spatial coverage of mass transit corridors in sprawling urban regions and inadequate first- and last-mile connectivity options ... -
Mixed Variational Approaches in Nonlinear Continuum Mechanics and Discretization by Finite Element Exterior Calculus
Numerical solution techniques for nonlinear elasticity have been an active area of research for a while. Right from the early days, it was recognized that constructing well-performing FE approximations for nonlinear ... -
Modelling and evaluation of nitrate transit times in groundwater systems
Transit time distribution is one of the fundamental descriptors of flow and transport behavior of catchments. Intensification of agriculture and consequent anthropogenic inputs of nitrate rich fertilizers in agricultural ... -
Experimental, Numerical and Probabilistic Analysis of Reinforced Anchors for Transmission Tower Foundations
The foundations of tall structures such as transmission towers are subjected to loads in three directions coming from wind and other environmental events. The use of anchors for application in transmission tower foundations ... -
Studies on Flexural Fatigue Behaviour of Plain Concrete – Mechanisms of Crack Growth, Effect of Loading Amplitude, Frequency and Notch Size
Concrete structures such as bridges, pavements and off shore structures are subjected to fluctuating loading throughout their service life. These fluctuating loads cause progressive internal damage to structures leading ... -
Comparison of Additive and Multiplicative Kinematics in Large Deformation Plasticity
The most widely used plasticity model in commercial finite element analysis software packages is the additive plasticity model. One of the more well-known alternatives to additive plasticity is multiplicative plasticity. ... -
Simulation of complex plastic flows in metal sliding and cutting
Metal manufacturing encompasses a broad range of mechanical transformation processes that shape native metal into useful forms. These processes generally involve the interaction of a hard tool with a specimen / workpiece, ... -
Effects of 3d Morphological Characteristics of Sand on Multi-scale Intergranular and Sand-geosynthetic Interactions
To understand the process of mobilization of shear strength in sands and sand-geosynthetic interfaces at a fundamental level, it is essential to precisely characterize the size and shape of the grains and the shear-induced ... -
Morphological Perspectives of Sand Liquefaction and its Mitigation
Liquefaction of soils under seismic conditions has profound implications for infrastructure resilience in earthquake-prone regions. Saturated loose cohesionless granular soils have the tendency to readily lose grain contacts ... -
Investigating and Modelling the Microscopic Pedestrian Behavioral Dynamics in Mass Religious Gatherings
Pedestrian models that can realistically reproduce observed pedestrian movement dynamics are crucial in facility planning and pre-event planning of crowded situations. Despite the elaborate arrangements, crowd disasters ... -
Micromechanics of Wedge and Cone Indentation of Metallic Specimens with Subsurface Voids
Near-surface voids and pores occur in metal parts manufactured by processes as diverse as casting, powder metallurgy, and additive manufacturing. These pores range in size from a few microns to a few mm, depending on the ... -
Evaluation Frameworks for Informed Multi-Site Multi-Variate Hydrological Assessment
The process of choosing a suitable hydrological model, calibrating it, and evaluating its performance poses intricate challenges for a modeler. The process of model selection is frequently influenced by the modeller's ... -
Experimental and Numerical Evaluation of Mechanical Response of Unsaturated Soils and Their Application to Embankments and Footings
Naturally, soils are rarely fully saturated, and climatic and environmental conditions frequently cause moisture content to change. Due to the varying climate changes and its effects on compacted engineering structures, ... -
