Available in PDF, EPUB and Kindle. Book excerpt: Interfaces exist in every geotechnical system in many forms and at multiple scales. Although historically, they are often considered to be the weak link in a system, particularly as the result of a number of unexpected catastrophic failures, new insight gained over the past twenty years by researchers around the world has shown that it is possible to select combinations of materials and design an engineered interface so that it is at least as strong as the surrounding materials. These new insights have been gained as a result of experimental study, numerical modeling and analytical investigation of successful and failed systems. While individual technical papers have been presented and/or published in various forums and proceedings over the years, no technical event has ever been convened for the sole purpose of allowing for exchange of information and ideas pertaining to geotechnical interfaces. The research symposium held in September 2008 in Atlanta Georgia, USA, in conjunction with the Fourth International Symposium on Deformation Characteristics of Geomaterials (IS Atlanta 2008) at the Georgia Institute of Technology on The Characterization and Behavior of Interfaces addressed this deficiency and the papers presented at that event are contained in this publication.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The notion of “interface” is a universal topic of research in material sciences. Interfaces are responsible for many of the magnetic, electrical, optical and mechanical properties of materials and therefore need to be characterize. The focus of this work is to bring a new understanding of the interfacial mechanical properties of materials by characterizing two industrial components which properties are governed by their interfaces. First, we address the notion of coating and adhesion by characterizing the hardness and microstructure of a 17-4PH steel substrate subjected to a grit blasting surface treatment followed by the deposition of a cermet coating by high velocity oxy-fuel (HVOF). The hardness was characterized using nanoindentation and the microstructure were imaged by optical and electron microscopy. The results showed a strong impact of the surface treatment on the interfacial microstructure and hardness of the substrate revealing a potential weakening of the interfacial adhesion because of it. Then, in light of the results gathered, a similar method was applied to the characterization of an aluminum foam. However, the aluminum foam is a much more complex material and requires a multiscale approach. The structure and microstructures were characterized by several techniques to account for the multiscale nature of the material. Similarly, the mechanical properties were determined by diverse procedures. The results unveil a particularly inhomogeneous material at all scales resulting in non-uniform mechanical properties. The strong interdependence of the macroscopic and microscopic properties is highlighted and gives a better understanding of the mechanical behavior of the foam.

Download or read book Modeling and Characterization of the Elastic Behavior of Interfaces in Nanostructured Materials written by Remi Dingreville and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, an innovative approach combining continuum mechanics and atomistic simulations is exposed to develop a nanomechanics theory for modeling and predicting the macroscopic behavior of nanomaterials. This nanomechanics theory exhibits the simplicity of the continuum formulation while taking into account the discrete atomic structure and interaction near surfaces/interfaces. There are four primary objectives to this dissertation. First, theory of interfaces is revisited to better understand its behavior and effects on the overall behavior of nanostructures. Second, atomistic tools are provided in order to efficiently determine the properties of free surfaces and interfaces. Interface properties are reported in this work, with comparison to both theoretical and experimental characterizations of interfaces. Specifically, we report surface elastic properties of groups 1011 transition metals as well as properties for low-CSL grain boundaries in copper. Third, we propose a continuum framework that casts the atomic level information into continuum quantities that can be used to analyze, model and simulate macroscopic behavior of nanostructured materials. In particular, we study the effects of surface free energy on the effective modulus of nano-particles, nanowires.
Download or read book Elastodynamic Characterization of Material Interfaces Using Spring Models written by Madhura Prashant Athale and published by . This book was released on 2017 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding wave phenomena at material interfaces is an important problem in non-destructive evaluation / material characterization. Modeling the behavior of the interface presents interesting opportunities in this field. The present work attempts to understand the effect of an interface on transient and steady-state wave propagation through a bi-material system. Horizontally polarized shear waves (SH) are chosen as candidates in the analysis. The interface itself is considered to be spring-like with non-linear load-displacement characteristics. The non-linear behavior of the spring can easily be treated as approximate linearized segments. Transient analytical solution forms for reflected and transmitted waves are obtained by considering linear spring interface model using Cagniard-de Hoop technique. Numerical results for time-harmonic SH wave interaction are obtained considering a non-linear spring model using perturbation technique. The methodology presented should enable a practicing engineer to draw insights into interface strength / damage.

Download or read book Characterization and Modification of Graphene Based Interfacial Mechanical Behavior written by Guorui Wang and published by Springer Nature. This book was released on 2020-08-21 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis shares new findings on the interfacial mechanics of graphene-based materials interacting with rigid/soft substrate and with one another. It presents an experimental platform including various loading modes that allow nanoscale deformation of atomically thin films, and a combination of atomic force microscopy (AFM) and Raman spectroscopy that allows both displacement and strain to be precisely measured at microscale. The thesis argues that the rich interfacial behaviors of graphene are dominated by weak van der Waals force, which can be effectively modulated using chemical strategies. The continuum theories are demonstrated to be applicable to nano-mechanics and can be used to predict key parameters such as shear/friction and adhesion. Addressing key interfacial mechanics issues, the findings in thesis not only offer quantitative insights in the novel features of friction and adhesion to be found only at nanoscale, but will also facilitate the deterministic design of high-performance graphene-based nanodevices and nanocomposites.
Download or read book Fluid Interfaces written by Eduardo Guzmán and published by MDPI. This book was released on 2021-03-02 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid interfaces are promising candidates for confining different types of materials, e.g., polymers, surfactants, colloids, and even small molecules, to be used in designing new functional materials with reduced dimensionality. The development of such materials requires a deepening of the physicochemical bases underlying the formation of layers at fluid interfaces as well as on the characterization of their structures and properties. This is of particular importance because the constraints associated with the assembly of materials at the interface lead to the emergence of equilibrium and features of dynamics in the interfacial systems, which are far removed from those conventionally found in traditional materials. This Special Issue is devoted to studies on the fundamental and applied aspects of fluid interfaces, and attempts to provide a comprehensive perspective on the current status of the research field.

Download or read book Surfaces and Interfaces in Ceramic and Ceramic Metal Systems written by Joseph Pask and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 17th University Conference on Ceramics, which also was the 7th LBL/MMRD International Materials Symposium, was held on the campus of the University of California at Berkeley from July 28 to August 1, 1980. It was devoted to the subject of surfaces and interfaces in ceramic and ceramic-metal systems. The program was timely and of great interest, as indicated by the large number of contributed papers, which included contributions from ten foreign countries. These proceedings are divided into the following categories dealing with the chemistry and physics of interfaces: calculations of interface/surface states, characterization of surfaces and inter faces, thermodynamics of interfaces, influence of surface and inter faces on selected ceramic processes, grain boundary structures, effects of grain boundaries on deformation and fracture, interfacial phenomena, formation of interfaces, development of adhesion, and reactions at interfaces. A number of papers deal specifically with the Si-Si02 interface, which probably has received more attention than any other because of its importance in the electronics industry. This coverage fulfills the principal objective of the symposium which was to explore and assess the current fundamental understand ing of interfaces and surfaces. A parallel objective of the symposium was fulfilled by a group of papers dealing with the correlation of interfacial characteris tics with mechanical behavior. This group includes papers dealing with the adherence of dissimilar materials at interfaces.
Download or read book Characterization of Polymer Blends written by Sabu Thomas and published by John Wiley & Sons. This book was released on 2014-10-28 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling the gap for a reference dedicated to the characterization of polymer blends and their micro and nano morphologies, this book provides comprehensive, systematic coverage in a one-stop, two-volume resource for all those working in the field. Leading researchers from industry and academia, as well as from government and private research institutions around the world summarize recent technical advances in chapters devoted to their individual contributions. In so doing, they examine a wide range of modern characterization techniques, from microscopy and spectroscopy to diffraction, thermal analysis, rheology, mechanical measurements and chromatography. These methods are compared with each other to assist in determining the best solution for both fundamental and applied problems, paying attention to the characterization of nanoscale miscibility and interfaces, both in blends involving copolymers and in immiscible blends. The thermodynamics, miscibility, phase separation, morphology and interfaces in polymer blends are also discussed in light of new insights involving the nanoscopic scale. Finally, the authors detail the processing-morphology-property relationships of polymer blends, as well as the influence of processing on the generation of micro and nano morphologies, and the dependence of these morphologies on the properties of blends. Hot topics such as compatibilization through nanoparticles, miscibility of new biopolymers and nanoscale investigations of interfaces in blends are also addressed. With its application-oriented approach, handpicked selection of topics and expert contributors, this is an outstanding survey for anyone involved in the field of polymer blends for advanced technologies.
Download or read book Character Computing written by Alia El Bolock and published by Springer Nature. This book was released on 2020-01-01 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book gives an introduction into the theory and practice of the transdisciplinary field of Character Computing, introduced by Alia El Bolock. The latest scientific findings indicate that “One size DOES NOT fit all” in terms of how to design interactive systems and predict behavior to tailor the interaction experience. Emotions are one of the essential factors that influence people’s daily experiences; they influence decision making and how different emotions are interpreted by different individuals. For example, some people may perform better under stress and others may break. Building upon Rosalind Picard’s vision, if we want computers to be genuinely intelligent and to interact naturally with us, we must give computers the ability to recognize, understand, even to have and express emotions and how different characters perceive and react to these emotions, hence having richer and truly tailored interaction experiences. Psychological processes or personality traits are embedded in the existing fields of Affective and Personality Computing. However, this book is the first that systematically addresses this including the whole human character; namely our stable personality traits, our variable affective, cognitive and motivational states as well as our morals, beliefs and socio-cultural embedding. The book gives an introduction into the theory and practice of the transdisciplinary field of Character Computing. The emerging field leverages Computer Science and Psychology to extend technology to include the whole character of humans and thus paves the way for researchers to truly place humans at the center of any technological development. Character Computing is presented from three main perspectives: ● Profiling and sensing the character ● Leveraging characters to build ubiquitous character-aware systems ● Investigating how to extend Artificial Intelligence to create artificial characters
