Mechanics of cutting in granular media
Cutting is an important deformation process encountered during many instances in the engineering of infrastructure, such as trawling, trenching, and excavation. This thesis presents the results of an experimental program ... -
Multiple Discrete-Continuous Choice Models with Flexible Specification of Constraints, Utility Forms, and Stochastic Distributions: Applications in Travel Behavior Research
Econometric choice models have been widely used in travel behaviour research to understand human activities, time-use, mobility choices, consumption, and related preferences. Most research in this area had focused on ... -
Multi-level Partitioning Algorithms & Reliability Analysis for Transit Networks
Public transit systems are an indispensable part of any metropolitan city. Its success depends on many factors, chief among which is the ease with which users can query for optimal journeys using mobile apps. Conventional ... -
Regional and Local-scale Analysis of Landslides Induced by Rainfall and Earthquakes
Landslides are major natural disasters which pose a significant risk to lives and infrastructure globally. As urbanization is increasing due to the increasing population in mountainous regions, the risk due to landslides ... -
Strain Rate, Volume Fraction and Notch Depth Effects on Fracture Properties of Fibrous Cementitious Composites
It is known that concrete is weak in tension. Steel Fibre Reinforced Concrete (SFRC) is an alternative cementitious composite to increase the tensile strength, energy absorption capacity and durability of concrete structures. ... -
New Approaches to At-site and Regional Frequency Analysis of Hydrologic Extremes in Peaks Over Threshold Framework
Frequency analysis procedures are widely used to quantify the risk associated with floods that have devastating consequences worldwide. Conventionally, the frequency analysis is performed based on the annual maximum series ... -
Deformation characteristics of soil under sequential dynamic torsional and cyclic axial loading
Earthquake-induced structural damages caused due to site effects, soil liquefaction failure, and associated excessive settlement are well-known worldwide. The primary controlling factor responsible for the superstructure’s ... -
Nonlocal continuum models for plasticity and damage
Nonlocal interactions of material points play a vital role in modelling certain important aspects of inelastic phenomena such as plasticity and damage in solids. For plasticity problems, nonlocal interactions allow ... -
Quasi-Static and Implicit-Dynamic Finite Element Solution of Large Deformation Elastic Adhesive Contacts Using a Volumetric Interaction Scheme
Adhesive forces, mediated by van der Waals’ and other interactions, dominate the contact response in the micron and sub-micron regimes. Understanding adhesion is especially important in biological systems (interaction of ... -
An Application of Resonant Column along with Bender Elements Tests for Assessing Dynamic Properties and Liquefaction Potential of Sand
For determining the response of foundation soils subjected to different kinds of vibrations emerging from (i) an occurrence of an earthquake, (ii) movements of trains over railways tracks, (iii) running of vehicles over ... -
Macroscopic crowd flow and risk modelling in mass religious gathering
Understanding the principles and applications of crowd dynamics in mass gatherings is very important, specifically with respect to crowd risk analysis and crowd safety. Historical trends from India and other countries ... -
Analysis of Fracture Processes in Steel Fibre Reinforced Cementitious Composites using Acoustic Emission Testing
Plain concrete has low tensile strength. Steel fibre reinforced concrete (SFRC) is an alternative to plain concrete. One of the major reasons of using the SFRC is due to its high tensile strength. The fracture process ... -
Constitutive Theories for Polymers Using Non-Classical Continuum Mechanics
This thesis is on the development of a few constitutive theories characterising the thermo-mechanical response of polymers. In proposing the theories, some aspects of non-classical continuum mechanics are used. The first ... -
Lower Bound Finite Element Limit Analysis for Solving Different Planar and Axisymmetric Stability Problems in Soil and Rock Media
The finite element limit analysis (FELA), which utilizes the concept of finite elements and an optimization procedure, is a very powerful technique to find an accurate solution of different stability problems in geomechanics. ... -
Simulation and Characterization of Streamflow Time Series
Streamflow can be partitioned into distinct time scales to better understand the underlying governing processes: fast flow, representing surface runoff controlled mainly by meteorological processes that operate over ... -
Reliability based analysis and design of slopes and tunnels in rock mass
Structures in rock mass such as slopes and tunnels form an important segment in the infrastructure development of a country. Rock mass consists of intact rock matrix with numerous discontinuities that can be represented ... -
Isogeometric based formulations for the bending analysis of laminated composite structural elements
Isogeometric analysis (IGA) is a family of numerical methods to solve boundary value problems. The founding principle of isogeometric methods is aimed at integrating computer aided design (CAD) with nite element method ... -
Studies on the behaviour of the fibre reinforced cement stabilised rammed earth
Cement stabilised rammed earth (CSRE) is a monolithic construction used for the loadbearing walls in the buildings and other structures. The soil, fine aggregates and cement form the basic materials for the CSRE construction. ... -
