Experimental studies on the fracture and fatigue failure processes under direct tension in quasi-brittle materials - Graphite and Concrete
Abstract Fatigue phenomenon is a gradual, permanent, micro structural change that takes place in a material due to the application of repeated loading. In the case of quasi-brittle materials like graphite and concrete, ... -
Experimental Studies on The Mechanical Behaviour of Cohesive Frictional Granular Materials
(2017-09-26)Thss thesis presents the results of an experimental programme on the static mono-tonic response of cohesive-frictional granular materials. The purpose of this experimental programme was to gain insight into the mechanical ... -
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 ... -
Exploring Hydrological Processes, Modeling Decisions, and Deep Learning for Improved Hydrologic Assessment
Hydrological modeling is complicated by the intricate challenges and uncertainties associated with understanding hydrological processes. This thesis aims at answering some of the key research questions related to ... -
Extra-cellular Polysaccharides and Microbially Induced Carbonate Cementation Using Indigenous Microbes in Cattle Manure
Soft soils are composed of large portions of silts and clay and are characterized by low strength and high compressibility owing to their high-water content. Biocementation techniques are emerging as a strong alternative ... -
Factors Affecting The Static And Dynamic Response Of Jointed Rock Masses
(2010-07-20)Infrastructure is developing at an extremely fast pace which includes construction of metros, underground storage places, railway bridges, caverns and tunnels. Very often these structures are found in or on the rock masses. ... -
Factors Controlling the Dispersivity of Soils and the Role of Zeta Potential
(2017-12-07)Most soil particles loses cohesion and split up the soil mass into individual soil grains when they come in contact with water and get saturated. In dispersive soils the particles detach more spontaneously from each other ... -
Factors Influencing Contaminant Transport in Vadose Zone of Near Surface Radioactive Waste Disposal Facility
Radioactive waste is generally classified as low and intermediate level waste (LILW) and high-level waste (HLW), based on their level of radioactivity and the time taken for decay. The low and intermediate level ... -
Fatigue Crack Growth in Roller-Rocker and Rocker Bearings of Railway Steel Bridges
Indian Railways comprise a major part of the infrastructure in India. Most of the transportation of raw materials, goods, and people from different parts of the country is done by the railways. To cope with the ever-increasing ... -
Field Investigations And Modeling of Flow in Vadose Zone in a Forested Watershed
(2017-10-18)The vadose zone is the unsaturated zone between the ground surface and water table. This zone is of much importance as it acts as a link between surface water and ground water. Knowledge of soil moisture in this zone is ... -
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 ... -
Formulations for solving geomechanics stability problems using stress characteristics and finite element limit analysis with power type and Mohr-Coulomb yield criteria
In geotechnical engineering, the stability analysis is often carried out to determine the ultimate collapse load that a geo-structure can possibly withstand. The accurate prediction of the exact collapse load is often very ... -
Fracture And Fatigue Behavior Of Concrete-Concrete Interfaces Using Acoustic Emission, Digital Image Correlation And Micro-Indentation Techniques
(2011-04-05)Currently, the maintenance and repair of civil engineering infrastructures (especially bridges and highways) have become increasingly important, as these structures age and deteriorate. Interface between two different mixes ... -
Fracture and Fatigue Behaviour of Notched Plain Concrete Beams: The Role of Theory of Critical Distances and Acoustic Emission
Concrete structures, including buildings, bridges, pavements, and offshore structures, face a wide range of loading conditions, both static and cyclic. When subjected to fatigue loading, the response of concrete elements ... -
Fracture Behaviour including Size Effect of Cement Stabilised Rammed Earth
(2018-01-30)Rammed earth is a monolithic construction formed by compacting processed soil in progressive layers. Rammed earth is used for the construction of load bearing walls, floors, sub base material in roadways, airport runways, ... -
Fracture Characteristics Of Self Consolidating Concrete
(2010-07-16)Self-consolidating concrete (SCC) has wide use for placement in congested reinforced concrete structures in recent years. SCC represents one of the most outstanding advances in concrete technology during the last two ... -
Fracture Energy And Process Zone In Plain Concrete Beams (An Experimental Study Including Acoustic Emission Technique)
(2013-05-20)Concrete, which was hitherto considered as a brittle material, has shown much better softening behavior after the post peak load than anticipated. This behavior of concrete did put the researchers in a quandary, whether ... -
Fracture Of Plain Concrete Beams Via Fractals
(2009-09-02)The quantitative description of rough fracture surfaces of concrete has been an important challenge for many years. Looking at the fracture surface of a concrete specimen, one realizes that the self-affine geometry of crack ...
