The study of buckling loads, which often hinges on numerical methods, is key in designing structural elements. But the need for analytical solutions in addition to numerical methods is what drove the creation of Exact Solutions for Buckling of Structural Members. It allows readers to assess the reliability and accuracy of solutions obtained by numerical methods. The author has attempted to gather and present as many exact buckling solutions as possible in one single volume for engineers and researchers. These buckling solutions of columns, beams, arches, ring plates, and shells should serve as benchmarks for checking the validity, convergence, and accuracy of numerical methods and solutions.

The main properties that make carbon nanotubes (CNTs) a promising technology for many future applications are: extremely high strength, low mass density, linear elastic behavior, almost perfect geometrical structure, and nanometer scale structure. Also, CNTs can conduct electricity better than copper and transmit heat better than diamonds. Therefore, they are bound to find a wide, and possibly revolutionary use in all fields of engineering. The interest in CNTs and their potential use in a wide range of commercial applications; such as nanoelectronics, quantum wire interconnects, field emission devices, composites, chemical sensors, biosensors, detectors, etc.; have rapidly increased in the last two decades. However, the performance of any CNT-based nanostructure is dependent on the mechanical properties of constituent CNTs. Therefore, it is crucial to know the mechanical behavior of individual CNTs such as their vibration frequencies, buckling loads, and deformations under different loadings. This title is dedicated to the vibration, buckling and impact behavior of CNTs, along with theory for carbon nanosensors, like the Bubnov-Galerkin and the Petrov-Galerkin methods, the Bresse-Timoshenko and the Donnell shell theory.

Within the last thirty years there is a growing acknowledgement that prevention of catastrophic failures necessitates engagement of a large pool of expertise. Herein it is not excessive to seek advice from disciplines like materials science, structural engineering, mathematics, physics, reliability engineering and even economics. Today’s engineering goals, independently of size; do not have the luxury of being outsideaglobalperspective.Survivaloftheintegratedmarketsand?nancialsystems require a web of safe transportation, energy production and product manufacturing. It is perhaps the ?rst decade in engineering history that multidisciplinary - proaching is not just an idea that needs to materialise but has matured beyond infancy. We can witness such transition by examining engineering job descriptions and postgraduate curricula. The undertaking of organising a conference to re?ect the above was not easy and de?nitely, not something that was brought to life without a lot of work and c- st mitment. The 1 Conference of Engineering Against Fracture from its conceptual day until completion was designed in a way of underlying the need of bringing all the key players on a common ground that once properly cultivated can ?ourish. To achieve that the conference themes were numerous and despite their, in principle notional differences, it was apparent that the attendees established such common ground through argumentation. The reader can see this from the variety of research areas re?ected by the works and keynote lecturers presented.

Students embarking on their studies in chemical, mechanical, aerospace, energy, and environmental engineering will face continually changing combustion problems, such as pollution control and energy efficiency, throughout their careers. Approaching these challenges requires a deep familiarity with the fundamental theory, mathematics, and physical concepts of combustion. Based on more than two decades of teaching experience, Combustion Science and Engineering lays the necessary groundwork while using an illustrative, hands-on approach. Taking a down-to-earth perspective, the book avoids heavy mathematics in the first seven chapters and in Chapter 17 (pollutants formation and destruction), but considers molecular concepts and delves into engineering details. It begins with an outline of thermodynamics; basics of thermochemistry and chemical equilibrium; descriptions of solid, liquid, and gaseous fuels; chemical kinetics and mass transfer; and applications of theory to practical systems. Beginning in chapter 8, the authors provide a detailed treatment of differential forms of conservation equations; analyses of fuel combustion including jet combustion and boundary layer problems; ignition; flame propagation; interactive and group combustion; pollutant formation and control; and turbulent combustion. In addition, this textbook includes abundant examples, illustrations, and exercises, as well as spreadsheet software in combustion available for download. This software allows students to work out the examples found in the text. Combustion Science and Engineering imparts the skills and foundational knowledge necessary for students to successfully approach and solve new problems.

Numerical and Analytical Methods with MATLAB® presents extensive coverage of the MATLAB programming language for engineers. It demonstrates how the built-in functions of MATLAB can be used to solve systems of linear equations, ODEs, roots of transcendental equations, statistical problems, optimization problems, control systems problems, and stress analysis problems. These built-in functions are essentially black boxes to students. By combining MATLAB with basic numerical and analytical techniques, the mystery of what these black boxes might contain is somewhat alleviated. This classroom-tested text first reviews the essentials involved in writing computer programs as well as fundamental aspects of MATLAB. It next explains how matrices can solve problems of linear equations, how to obtain the roots of algebraic and transcendental equations, how to evaluate integrals, and how to solve various ODEs. After exploring the features of Simulink, the book discusses curve fitting, optimization problems, and PDE problems, such as the vibrating string, unsteady heat conduction, and sound waves. The focus then shifts to the solution of engineering problems via iteration procedures, differential equations via Laplace transforms, and stress analysis problems via the finite element method. The final chapter examines control systems theory, including the design of single-input single-output (SISO) systems. Two Courses in One Textbook The first six chapters are appropriate for a lower level course at the sophomore level. The remaining chapters are ideal for a course at the senior undergraduate or first-year graduate level. Most of the chapters contain projects that require students to write a computer program in MATLAB that produces tables, graphs, or both. Many sample MATLAB programs (scripts) in the text provide guidance on completing these projects.

Research and Applications in Structural Engineering, Mechanics and Computation contains the Proceedings of the Fifth International Conference on Structural Engineering, Mechanics and Computation (SEMC 2013, Cape Town, South Africa, 2-4 September 2013). Over 420 papers are featured. Many topics are covered, but the contributions may be seen to fall into one of four broad themes of the conference, namely: (i) structural mechanics (dynamics, vibration, seismic response, statics, bifurcation, buckling, stability, impact response, contact mechanics, fluid-structure interaction, soil-structure interaction, etc); (ii) mechanics of materials (elasticity, plasticity, fracture, damage, fatigue, creep, shrinkage, etc); (iii) modelling and testing (finite-element modelling, numerical methods, numerical simulations, experimental methods, experimental testing); (iv) structural-engineering practice (planning, analysis, design, construction, maintenance, repair, retrofitting, decommissioning). Not only do the considerations cover many types of engineering structures (buildings, bridges, tunnels, towers, space frames, roofs, foundations, shells, plates, mechanical assemblies, etc), they also span a diversity of engineering materials ranging from the traditional to the novel: steel, concrete, timber, masonry, aluminium, special alloys, glass, composites, functionally-graded materials, smart materials, etc. Two versions of each paper are available. The printed book features 2-page versions of the papers, intended to be concise but sufficiently informative summaries of the full papers. Details may be seen in the full papers, which are carried on the accompanying CD-ROM. Research and Applications in Structural Engineering, Mechanics and Computation is of interest to civil, structural, mechanical, marine and aerospace engineers concerned with the modelling, analysis, design, construction and maintenance of engineering structures. Researchers, practitioners and academics in these discipines will find the book useful. The SEMC international conferences, inaugurated in 2001, aim at bringing together from around the world academics, researchers and practitioners in the broad fields of structural mechanics, associated computation and structural engineering, to review recent achievements in the advancement of knowledge and understanding in these areas, share the latest developments, and address the challenges that the present and the future pose.
