Spacetime damage-based cohesive model for elastodynamic fracture with dynamic contact
… and a variety of numerical methods for its modeling have been proposed. This thesis presents the formulation and implementation of an interfacial-damage, cohesive-fracture model, including contact and friction effects, for dynamic failure of brittle materials. The model is implemented within …

STRUCTURAL RETROFITTING OF CONCRETE BEAMS USING FRP - Debonding Issues
A 3D nonlinear finite element analysis modelling framework was developed for simulating the behaviour of beams retrofitted with fibre reinforced polymer (FRP). The ABAQUS program was used for this purpose. Concrete was modelled using a plastic damage model. Steel bars were modelled as an elastic …

Sustainable and Environmentally Responsible Future for Businesses and Society
… frameworks. This study integrates them into a cohesive model of responsible management. The findings suggest that financial and digital innovation are potent drivers of climate resilience and ecological sustainability, which require robust governance. Knowledge-driven transitions, such asthose …

Fracture analysis of carbon fiber/epoxy matrix interface through microbond and cruciform tests
… final displacement to failure), that define the cohesive failure model used to simulate the initiation and propagation of the crack front along the interface. Emphasis is placed in this study on characterizing the interfacial failure properties of three composite systems, defined by the surface …

Simulation of Fracture of Concrete Using Micropolar Peridynamics
… the thesis is to develop a constitutive damage model for simulating tensile fracture of concrete using the micropolar peridynamics model. Micropolar peridynamics was proposed by Gerstle in 2007 as a generalization to the bond based peridynamics method introduced by Silling in 2000, which was …

Mechanisms of Human LARP6 Nuclear Export
… were to combine these cellular and structural models of LARP6 localization into a cohesive model of LARP6 function. First, to test if LARP6 export is mediated by the nuclear export in Chromosome Region Maintenance 1(CRM1) in vivo, we performed inhibition studies in cell lines that endogenously …

Sancti Episcopi : a study of the canonization of bishops in England, 1170-1320.
… to see if they conformed to or exhibited any cohesive ‘model’ of sanctity. It also examines Stephen Langton, one of the bishops around whom a local cult developed, but who did not receive a process of canonization, in order to show how bishops changed how holiness could be perceived and …

Fracture analysis in biomimetic Bouligand architectures
… I employ finite element simulations with a 3D cohesive model to simulate the crack growing process. Our study reveals that crack twisting offers additional fracture resistant mechanisms in addition to increasing the effective area of crack growth. Moreover, I develop a theoretical model to …

Undoings: A Feminist Art Practice Investigating Female Sexed Corporeality and Othered Phenomenological Bodies
… sociocultural context, I develop a unified and cohesive model of mind and body in order to conceive of female sexed subjects as having specific relationalities and different strategies or alternative desires to that of the universal, neutral, male body. In the course of my research, I determine …

Dynamic delamination of patterned thin films
… solutions for the substrate and finite element model for the thin film. Cohesive elements are introduced along the bi-material interface to capture the decohesion process. The important role of the inertia on the crack extension and the mixed-mode failure are demonstrated by observing the …

Computational modeling of laser-induced delamination testing of thin films
… The objective of the current effort is to model the effect of residual stresses on the dynamic delamination of thin films. Residual stresses can be high enough to affect the crack advance and the mode mixity of the delimitation event, and must therefore be adequately modeled to make …

A proposal for model-based automation of enterprise service change management processes
… cornerstones of this proposal is an information model of all the relevant management information. The proposed model builds upon the common ground of the main information model standards to characterize both the logical artifacts, originated from the service development process, and the managed …
