Finite Element Limit Analysis for Solving Different Axisymmetric Stability Problems in Geomechanics : Formulations and Solutions
(2017-11-15)
Limit analysis is a very powerful tool to find accurate solutions of several geotechnical stability problems. This analysis is based on the theory of the plasticity and it provides two limiting solutions within lower and ...
Impacts of Climate Change on IDF Relationships for Design of Urban Stormwater Systems
(2018-01-29)
Increasing global mean temperature or global warming has the potential to affect the hydrologic cycle. In the 21st century, according to the UN Intergovernmental Panel on Climate Change (IPCC), alterations in the frequency ...
Studies on the Modeling of Fatigue Crack Growth and Damage in Concrete : A Thermodynamic Approach
(2018-01-11)
Fatigue in concrete is a complex phenomenon involving formation of microcracks, their coalescence into major crack and simultaneous formation of the fracture process zone ahead of the crack tip. Complex phenomena are best ...
A Hydroclimatological Change Detection and Attribution Study over India using CMIP5 Models
(2017-11-14)
As a result of increase in global average surface temperature, abnormalities in different hydroclimatic components such as evapotranspiration, stream flow and precipitation have been experienced. So investigation has to ...
Ground Improvement using 3D-Cellular Confinement Systems : Experimental and Numerical Studies
(2018-01-09)
The various aspects of the 3D cellular confinement systems (geocells) subjected to static loading are comprehensively studied with the help of experimental and numerical studies. The performances of the geocells were ...
Geotechnical Behaviour Of Soil Containing Mixed Layered Illite-Smectite Contaminated With Caustic Alkali
(2008-01-29)
The aim of the thesis has been to evaluate and understand the effect of caustic alkali solution of varying composition on the behaviour of expansive soil containing mixed layered minerals. Mixed layered minerals are formed ...
Shear Behaviour of Sand-geosynthetic Interfaces Based on Size And Morphology of Sand Particles and Surface Roughness of Geosynthetics
(2018-01-01)
Geosynthetics are used in conjunction with soil/particulate materials to serve various functions like reinforcement, drainage, filtration and containment. The shear behavior of soil-geosynthetic interfaces hugely depends ...
Class-F Fly Ash and Ground Granulated Blast Furnace Slag (GGBS) Mixtures for Enhanced Geotechnical and Geoenvironmental Applications
(2018-01-11)
Fly ash and blast furnace slag are the two major industrial solid by-products generated in most countries including India. Although their utilization rate has increased in the recent years, still huge quantities of these ...
Computational Studies on the Mechanics of Nanotubes and Nanocomposites
(2018-01-09)
The discovery of carbon nanotubes (CNTs) in 1991 by Iijima revealed the possibility of ultra-strong materials exploiting the properties of materials at smaller length scales. The superior strength, stiffness, and ability ...
Synthesis and Characterization of Geopolymers as Construction Materials
(2018-01-09)
Geopolymers are a relatively new class of materials that have many broad applications, including use as substitute for ordinary Portland cement (OPC), use in soil stabilisation, fire resistant panels, refractory cements, ...
