Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Wave propagation is an exciting eld having applications cutting across many disciplines. In the eld of structural engineering and smart structures, wave propagation based tools have found increasing applications especially in the areaofstructuralhealthmonitoringandactivecontrolofvibrationsandnoise. Inaddition,therehasbeentremendousprogressintheareaofmaterialscience , wherein a new class of structural materials is designed to meet the parti- lar application. In most cases, these materials are not isotropic as in metallic structures. They are either anisotropic (as in the case of laminated composite structures) or inhomogeneous (as in the case of functionally graded mate- als). Analysis of these structures is many orders more complex than that of isotropic structures. For many scientists/engineers, a clear di erence between structural dynamics and wave propagation is not evident. Traditionally, a structural designer will not be interested in the behavior of structures beyond certain frequencies, which are essentially at the lower end of the frequency scale. For such situations, available general purpose nite element code will satisfy the designer's requirement. However, currently, structures are required tobedesignedtosustainverycomplexandharshloadingenvironments. These loadings are essentially multi-modal phenomena and their analysis falls under the domain of wave propagation rather than structural dynamics. Evaluation of the structural integrity of anisotropic and inhomogeneous structures s- jected to such loadings is a complex process. The currently available analysis tools are highly inadequate to handle the modeling of these structures. In this book, we present a technique called the 'Spectral Finite Element Method',whichwebelievewilladdresssomeoftheshortcomingsoftheexisting analysis tools.

Buch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The use of composites and functionally graded materials (FGMs) in structural applications has increased. FGMs allow the user to design materials for a specified functionality and have many uses in structural engineering. However, the behaviour of these structures under high-impact loading is not well understood.This book is the first to apply the Spectral Finite Element Method (SFEM) to inhomogeneous and anisotropic structures in a unified and systematic manner. It focuses on some of the problems with this media which were previously thought unmanageable. Types of SFEM for regular and damaged 1-D and 2-D waveguides, solution techniques, methods of detecting the presence of damages and their locations, and methods for controlling the wave propagation responses are discussed. Tables, figures and graphs support the theory and case studies are included.This book is of value to senior undergraduates and postgraduates studying in this field, and researchers and practicing engineers in structural integrity.

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The complexity of the problem in three dimensional domains can only be captured in higher-order polynomial equations, and FEM is not efficient to integrate higher-order polynomial equations. Spectral-element method (SEM) has excellent error properties (exponential convergence) being the fastest possible: 1) geometrical flexibility, 2) high computational efficiency and 3) reliable spectral accuracy. SEM combines the flexibility of FEM with the accuracy of a spectral approach, adopting the hexahedral elements satisfactorily. A low-order FEM is not suitable for greater numerical stability and accuracy. With the application of h- (meshing) and p- (mapping) refinement techniques, SEM performs to be an efficient method over the existing FEM. This work is important to evaluate some fundamental issues related to vegetated and barren slopes. It explores the suitability of stochastic process on slope stability, the soil-root interaction considering progressive failure and three major limitations of the infinite slope method. This work also includes to a practical problem of cut slopes in road opening to minimize the construction risk and design the safe and economic slopes.
