Download or read book Machining Composites Materials written by J. Paulo Davim and published by John Wiley & Sons. This book was released on 2013-10-28 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the application of composite materials hasincreased in various areas of science and technology due to theirspecial properties, namely for use in the aircraft, automotive,defence, aerospace and other advanced industries. Machiningcomposite materials is quite a complex task owing to itsheterogenity, and to the fact that reinforcements are extremelyabrasive. In modern engineering, high demands are placed oncomponents made of composites in relation to their dimensionalprecision as well as their surface quality. Due to these potentialapplications, there is a great need to understand the questionsassociated with machining composite materials. This book aims to provide the fundamentals and the recentadvances in the machining of composite materials (polymers, metalsand ceramics) for modern manufacturing engineering. The three partsof the book cover the machining of polymeric, metal and ceramicmatrix composites. This book can be used as a text book for the final year of anundergraduate engineering course or for those studyingmachining/composites at the postgraduate level. It can also serveas a useful work of reference for academics, manufacturing andmaterials researchers, manufacturing and mechanical engineers, andprofessionals in composite technology and related industries.

Download or read book Machining written by J. Paulo Davim and published by Springer Science & Business Media. This book was released on 2008-07-11 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Machining is one of the most important manufacturing processes. Parts manufactured by other processes often require further operations before the product is ready for application. “Machining: Fundamentals and Recent Advances” is divided into two parts. Part I explains the fundamentals of machining, with special emphasis on three important aspects: mechanics of machining, tools, and work-piece integrity. Part II is dedicated to recent advances in machining, including: machining of hard materials, machining of metal matrix composites, drilling polymeric matrix composites, ecological machining (minimal quantity of lubrication), high-speed machining (sculptured surfaces), grinding technology and new grinding wheels, micro- and nano-machining, non-traditional machining processes, and intelligent machining (computational methods and optimization). Advanced students, researchers and professionals interested or involved in modern manufacturing engineering will find the book a useful reference.

Download or read book Causal Analysis in Population Studies written by Henriette Engelhardt and published by Springer Science & Business Media. This book was released on 2009-05-05 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central aim of many studies in population research and demography is to explain cause-effect relationships among variables or events. For decades, population scientists have concentrated their efforts on estimating the ‘causes of effects’ by applying standard cross-sectional and dynamic regression techniques, with regression coefficients routinely being understood as estimates of causal effects. The standard approach to infer the ‘effects of causes’ in natural sciences and in psychology is to conduct randomized experiments. In population studies, experimental designs are generally infeasible. In population studies, most research is based on non-experimental designs (observational or survey designs) and rarely on quasi experiments or natural experiments. Using non-experimental designs to infer causal relationships—i.e. relationships that can ultimately inform policies or interventions—is a complex undertaking. Specifically, treatment effects can be inferred from non-experimental data with a counterfactual approach. In this counterfactual perspective, causal effects are defined as the difference between the potential outcome irrespective of whether or not an individual had received a certain treatment (or experienced a certain cause). The counterfactual approach to estimate effects of causes from quasi-experimental data or from observational studies was first proposed by Rubin in 1974 and further developed by James Heckman and others. This book presents both theoretical contributions and empirical applications of the counterfactual approach to causal inference.

Download or read book Fire Design of Concrete Structures Materials Structures and Modelling written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2007-01-01 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire design of concrete structures has emerged in recent years as a high profile subject of great interest to both experts and the public. This has been largely prompted by severe damage to concrete in a number of recent tunnel fires, as well as a considerable amount of research and development that has taken place world-wide. fib Task Group 4.3, "Fire Design of Concrete Structures", therefore took the initiative to develop this bulletin in order to present the results of this international research to a wider group of concrete professionals. The report presents a general brief outline of the effect of fire on both concrete material and concrete structures, with emphasis placed on the important developments of the past few years, namely: (a) the increasing use of high strength concrete (HSC) in buildings, tunnels and bridges; (b) the growing acceptance of the use of performance based fire engineering calculations for the structural analysis and design against fire; (c) the problem of, and solutions to, explosive spalling; and (d) fires in tunnels. This report is not intended to be an exhaustive review of the effect of fire on concrete and concrete structures, nor to present a database of properties at high temperature. Instead, the main aims of this document are to present recent trends and developments, highlight key influencing factors, bring together the disparate but related issues in one short document, highlight the deficiencies in current practice and point to the future. The basic principles of performance based codes and fire engineering are also presented on the assumption that the reader is not a specialist in this field.
