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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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. ... -
Subsurface Profiling of Shallow Bedrock Sites by Integrated Approach and Site-specific 2d Site Response Analysis
Estimation of reliable site effects and amplifications are important for seismic design. There are several 1D and 2D large scale site response analyses were reported in the literature and very limited shallow bedrock small ... -
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 ...
