Structural Reliability Estimation Using Markov Chain Splitting and Girsanov’s Transformation Based Methods
The work reported in this thesis is in the area of Monte Carlo simulation based methods for structural reliability estimation with special focus on strategies to reduce sampling variance of the estimator for the probability ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
