Fracture and Deformation in Bulk Metallic Glasses and Composites
(2018-01-11)Plastic flow in bulk metallic glasses (BMGs) localizes into narrow bands, which, in the absence of a microstructure that could obstruct them, propagate unhindered under tensile loading. In constrained deformation conditions ... -
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 and indentation behavior of shape memory alloys
Shape memory alloys (SMAs) are metallic systems capable of recovering large strains, typically in the range of 7 to 10%. A clear understanding of the fracture behaviour of SMAs is crucial to prevent failures, especially ... -
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 ... -
Fracture Processes in Sustainable Fibrous Cementitious Composites: Insights from Statistical Mechanics and Natural Time Analysis
In recent years, there has been a growing demand in the construction industry for slender, durable, and high performance structural elements. This has led to the development of an advanced cementitious composite material ... -
A Framework for Effectiveness-based Sustainability Assessment in Manufacturing – A Product Life Cycle Approach
In recent decades, various human health impacts and environmental concerns (e.g., microplastic pollution, chemical exposure, biodiversity loss) associated with manufacturing/product life cycles have surfaced, threatening ... -
A Framework for Evaluating Hydrologic Risk of Dams and Dam-Break Floods Under Data-Sparse and Climate Change Scenarios
Design Flood Hydrograph (DFH) desirable for studies related to the planning, design, operation, and risk assessment of a dam is often derived using the Unit Hydrograph (UH) approach. It involves the convolution of UH of ... -
A framework for optimizing immunotherapy for long-term control of HIV
HIV infects around 1 million people every year. Antiretroviral therapy (ART) is used to suppress viral replication and control disease progression but it cannot eradicate the virus. ART is therefore lifelong. Today, e ... -
A Framework to Measure the Socio-Economic Impact of Development Programs Using Malmquist Index
(2018-06-08)The main objective of this research is to evaluate the socio economic impact of the development programs like MGNREGA, JnNURM and development of Roads project, on the intended target area. The entire thesis can be divided ... -
Frequency Analysis of Floods - A Nanoparametric Approach
(2018-04-18)Floods cause widespread damage to property and life in different parts of the world. Hence there is a paramount need to develop effective methods for design flood estimation to alleviate risk associated with these extreme ... -
Frequency-Tuning and Dynamic Simulation of Electrostatically Actuated Beams
(2018-01-03)The resonance frequency of electrostatically actuated micromachined beams can be tuned substantially by applying a DC voltage bias, first by decreasing the frequency until the onset of pull-in and then by increasing it by ... -
Frictional-kinetic models for steady cohesionless granular flow through a wedge-shaped hopper
The present work attempts to combine a newly developed kinetic constitutive theory with an older frictional theory to model.the two-dimensional gravity flow of a cohesionless granular material such as sand through a ... -
From Particles to People: Vicsek-Inspired Behavioural Modelling Frameworks
In this thesis, we develop different modelling frameworks to capture the processes of opinion formation and disease spread. The common theme binding them is a nearest-neighbour-based interaction rule; while the closeness ... -
From Sanitation to Soil: Evaluating Faecal Sludge-Based Amendments for Nutrient Circularity and Sustainable Agriculture
Globally, especially across developing regions, cities face a dual challenge: managing faecal sludge (FS) from on-site sanitation systems in a safe and sustainable manner, while simultaneously restoring soils degraded by ...
