Book Description
In this study, a combination of experiments and analyses are performed to characterize the structural response of two variable stiffness composite panels to a series of thermal and mechanical loads. This characterization covers all phases of the structure's lifetime from design through global failure. These panels are advanced composite structures in which the fiber orientation angle varies continuously as tows are laid down along predefined curvilinear paths within each ply. The panels are manufactured from AS4/977-3 graphite-epoxy prepreg using an advanced tow placement system. Both variable stiffness panels have the same nominal layup, but one panel (the panel with overlaps) has overlapping tow bands of varying thickness and the other panel (the panel without overlaps) has a theoretically uniform-thickness laminate. A conventional uniform-thickness panel with a straight-fiber [ 45]5s layup (the baseline panel) is also evaluated..."

Book Description
Heat transfer is involved in numerous industrial technologies. This interdisciplinary book comprises 16 chapters dealing with combined action of heat transfer and concomitant processes. Five chapters of its first section discuss heat effects due to laser, ion and plasma-solid interaction. In eight chapters of the second section engineering applications of heat conduction equations to the curing reaction kinetics in manufacturing process, their combination with mass transport or ohmic and dielectric losses, heat conduction in metallic porous media and power cables are considered. Analysis of the safety of mine hoist under influence of heat produced by mechanical friction, heat transfer in boilers and internal combustion engine chambers, management for ultrahigh strength steel manufacturing are described in this section as well. Three chapters of the last third section are devoted to air cooling of electronic devices.

Book Description
This book is written to introduce the application of high-performance composite materials such as fiber reinforced polymers, functionally graded composites, and sustainable fiber reinforced composites for development of thin-walled plated structures, beams, girders, and deck structures subjected to different kinds of loads. This book also includes test cases and its validation with finite element method using general purpose commercial computer software. Moreover, the book also deals with design methodology of advanced composite materials based on different applications. The comprehensive overview of the state-of-the-art research on the high-performance composite structures dealing with their stability, response, and failure characteristics will be of significant interest to scientists, researchers, students, and engineers working in the thrust area of advanced composite structures. This book is also helpful for Ph.D. candidates for developing their fundamental understanding on high-performance composite structures, and it will also appropriate for master- and undergraduate-level courses on design of composite structures especially for Civil Engineering Infrastructures.

Book Description
STRUCTURAL ANALYSIS WITH THE FINITE ELEMENT METHOD Linear Statics Volume 1 : The Basis and Solids Eugenio Oñate The two volumes of this book cover most of the theoretical and computational aspects of the linear static analysis of structures with the Finite Element Method (FEM). The content of the book is based on the lecture notes of a basic course on Structural Analysis with the FEM taught by the author at the Technical University of Catalonia (UPC) in Barcelona, Spain for the last 30 years. Volume1 presents the basis of the FEM for structural analysis and a detailed description of the finite element formulation for axially loaded bars, plane elasticity problems, axisymmetric solids and general three dimensional solids. Each chapter describes the background theory for each structural model considered, details of the finite element formulation and guidelines for the application to structural engineering problems. The book includes a chapter on miscellaneous topics such as treatment of inclined supports, elastic foundations, stress smoothing, error estimation and adaptive mesh refinement techniques, among others. The text concludes with a chapter on the mesh generation and visualization of FEM results. The book will be useful for students approaching the finite element analysis of structures for the first time, as well as for practising engineers interested in the details of the formulation and performance of the different finite elements for practical structural analysis.
