This volume provides a concise, historical review of the methods of structural analysis and design - from Galileo in the seventeenth century, to the present day. Through it, students in structural engineering and professional engineers will gain a deeper understanding of the theory behind the modern software packages they use daily in structural design. This book also offers the reader a lucid examination of the process of structural analysis and how it relates to modern design. The first three chapters cover questions about the strength of materials, and how to calculate local effects. An account is then given of the development of the equations of elastic flexure and buckling, followed by a separate chapter on masonry arches. Three chapters on the overall behaviour of elastic structures lead to a discussion of plastic behaviour, and a final chapter indicates that there are still problems needing solution.
When many polymers are heated they transform directly into carbons, without passing through an intermediate liquid paste. Such carbons are termed polymetric carbons. Phenolic resins yield an isotropic impervious black glassy carbon which is hard enough to scratch window glass and has interesting electronic properties. polyacrylonitrile fibres yield carbon fibre with enormous stiffness and strength. Combinations of the two produce the strongest carbon material (carbon-fibre-reinforced carbon). Carbon-fibre-reinforced plastics are revolutionary low density-high-stiffness materials. This 1976 book brings together data from the authors' work to describe the manufacture of polymetric carbons. It provides a description of physical, mechanical and chemical properties which are related as closely as possible to the revealed structure. Emphasis is placed on the more interesting aspects, such as development of high-strength, high-stiffness material, the semi-conducting behaviour of intermediate

This book teaches the principles of soil mechanics to undergraduates, along with other properties of engineering materials, to which the students are exposed simultaneously. Using the critical state method of soil mechanics to study the mechanical behavior of soils requires the student to consider density alongside effective stresses, permitting the unification of deformation and strength characteristics. This unification aids the understanding of soil mechanics. This book explores a one-dimensional theme for the presentation of many of the key concepts of soil mechanics - density, stress, stiffness, strength, and fluid flow - and includes a chapter on the analysis of one-dimensional consolidation, which fits nicely with the theme of the book. It also presents some theoretical analyses of soil-structure interaction, which can be analyzed using essentially one-dimensional governing equations. Examples are given at the end of most chapters, and suggestions for laboratory exercises or dem
This book provides an introduction to the structural ceramics, their processing and properties. Five important groups of materials, porcelain, alumina, silicon carbide, silicon nitride and zirconia, are presented as case studies. Historical developments, the properties of constituent components, and relationships between production methods, resulting microstructures, and materials properties, are explained. The structural ceramics have many commercial applications, ranging from high voltage insulation and hot-gas filtration, to metal machining tools and surgical implants. These applications depend on combinations of chemical, physical and mechanical properties, which include structural stability over wide temperature ranges, strength, hardness, and resistance to wear. Over 200 diagrams and photographs provide visual aids to learning, and end of chapter summaries pull together key points. With numerous review questions to test understanding of the topics covered, and extensive referenci

High-temperature structural intermetallics continue to be an active field of research because they offer the promise of structural properties, oxidation resistance and service temperatures exceeding those of conventional metals and alloys. However, they also present problems with respect to their understanding and processing. Current research into aluminide- and silicide-based materials illustrates this point very well. Continuing advances require basic studies to support alloy development as well as the identification and exploration of applications. This book, first published in 2001, provides a representative cross-section of research carried out and should be of interest to a wide range of readers. The most 'popular' material continues to be TiAl, which is beginning to find applications as a light-weight, high-strength, oxidation resistant structural material. There is renewed interest in structural silicides with melting points on the order of 2000%C. Examples include intermetalli
Fracture mechanics studies the development and spreading of cracks in materials. The study uses two techniques including analytical and experimental solid mechanics. The former is used to determine the driving force on a crack and the latter is used to measure material's resistance to fracture. The text begins with a detailed discussion of fundamental concepts including linear elastic fracture mechanics (LEFM), yielding fracture mechanics, mixed mode fracture and computational aspects of linear elastic fracture mechanics. It explains important topics including Griffith theory of brittle crack propagation and its Irwin and Orowan modification, calculation of theoretical cohesive strength of materials through an atomic model and analytical determination of crack tip stress field. This book covers MATLAB programs for calculating fatigue life under variable amplitude cyclic loading. The experimental measurements of fracture toughness parameters KIC, JIC and crack opening displacement (COD)
This book combines the proceedings of Mechanical Behavior of Nanomaterials - Experiments and Modeling, and Plasticity in Confined Volumes - Modeling and Experiments. These two symposia brought together researchers to exchange ideas about the mechanical behavior of materials where size, be it microstructural or geometric, plays an important role. Firstly it focuses on understanding the mechanical behavior of nanostructured materials, such as nanoscale thin films, nanowires, nanotubes, and nanoparticles, as well as nanoporous, nanograined and nanotwinned materials. Such materials with submicron length scales are important building blocks for next-generation functional devices and materials systems. The second focus is on understanding how micron and submicron external and internal microstructural-length scales play a defining role in the strength and ductility of a material. Modern simulation methods have revealed a diverse range of atomic and mesoscale processes that can contribute to t
Landslides are caused by a failure of the mechanical balance within hillslopes. This balance is governed by two coupled physical processes: hydrological or subsurface flow and stress. The stabilizing strength of hillslope materials depends on effective stress, which is diminished by rainfall. This book presents a cutting-edge quantitative approach to understanding hydro-mechanical processes across variably saturated hillslope environments and to the study and prediction of rainfall-induced landslides. Topics covered include historic synthesis of hillslope geomorphology and hydrology, total and effective stress distributions, critical reviews of shear strength of hillslope materials and different bases for stability analysis. Exercises and homework problems are provided for students to engage with the theory in practice. This is an invaluable resource for graduate students and researchers in hydrology, geomorphology, engineering geology, geotechnical engineering and geomechanics and for
The 2006 edition of this authoritative guide on liquid crystalline polymer (LCP) science was produced in response to the wealth of new material generated in the field. It takes the reader through the theoretical underpinnings to real-world applications of LCP technology in a logical, well-integrated manner. A chapter on liquid biopolymers has been introduced, whilst the in-depth discussion on applications describes not only maturing fields of high strength structural LCPs, but also a detailed analysis of the developing area of functional materials. The in-depth coverage and detailed glossary establishes this as an indispensable text for graduate students and researchers in the polymer field, as well as being of interest to those working in chemistry, physics and materials science.
