This book was released on 2013-06-12 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing is the basic industrial activity generating real value. Cutting and abrasive technologies are the backbone of precision production in machine, automotive and aircraft building as well as of production of consumer goods. We present the knowledge of modern manufacturing in these technologies on the basis of scientific research. The theory of cutting and abrasive processes and the knowledge about their application in industrial practice are a prerequisite for the studies of manufacturing science and an important part of the curriculum of the master study in German mechanical engineering. The basis of this book is our lecture “Basics of cutting and abrasive processes” (4 semester hours/3 credit hours) at the Leibniz University Hannover, which we offer to the diploma and master students specializing in manufacturing science.

Download or read book High Performance and Optimum Design of Structures and Materials II written by S. Hernández and published by WIT Press. This book was released on 2016-11-28 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containing papers from the 2nd High Performance Design of Structures and Materials and the Optimum Design of Structures conference, following the success of a number of meetings since 1989, this book will be of interest to those in any engineering field. The use of novel materials and new structural concepts nowadays is not restricted to highly technical areas like aerospace, aeronautical applications or the automotive industry, but affects all engineering fields including those such as civil engineering and architecture. Most high performance structures require the development of a generation of new higher performance sustainable materials, which can more easily resist a range of external stimuli or react in a non-conventional manner. Emphasis is placed on intelligent structures and materials as well as the application of computational methods for their modelling, control and management. Optimisation problems of interest involve those related to size, shape and topology of structures and materials. Optimisation techniques have much to offer to those involved in the design of new industrial products. The development of new algorithms and the appearance of powerful commercial computer codes with easy to use graphical interfaces have created a fertile field for the incorporation of optimisation into the design process in all engineering disciplines. The book addresses the topic of design optimisation with welcomed contributions on numerical methods, different optimisation techniques and new software. Several of the topics covered are: Composite materials and structures; Material characterisation; Experiments and numerical analysis; Transformable structures; Environmentally friendly and sustainable structures; Evolutionary methods in optimisation; Aerospace structures; Biomechanics application and Pneumatic structures.

Available in PDF, EPUB and Kindle. Book excerpt: Volume is indexed by Thomson Reuters CPCI-S (WoS). The modelling of Machining Operations has become very widespread today, with many researchers developing models with which to predict metal-cutting performance. The aim here is to provide an answer to the challenges presented by the machining industry, which is presently facing very tight economical and environmental constraints. The collection of over 100 peer-reviewed papers covers twelve research topics, including: “Analytical and Numerical Modelling”; “Cutting Fundamentals: Input Parameters”; “Cutting Fundamentals: Experimental Validation”; “Surface Integrity”; “Surface Topography”; “Tool Wear and Tool Life”; “Dynamics and Stability”; “High-Speed Machining and 5-Axes Machining”; “Abrasive Machining”; “Ultra-Precision and Micromachining”; “Computer-Aided Manufacturing (CAM)”; “Experimental: Non-Conventional Machining”. This work will thus constitute an invaluable handbook on the subject.

Available in PDF, EPUB and Kindle. Book excerpt: Since its inception in 1991, EUROMAT has been held each year on behalf of the Federation of European Materials Societies (FEMS), and alternates between general and topical prospectives. This year's theme, Advances in Mechanical Behaviour, Plasticity and Damage, was proposed by the Societe Francaise de Metallurgie et de Materiaux (SF2M) to FEMS.This publication contains a selection of papers presented at the EUROMAT 2000 Conference, held in Tours, France on 7-9 November 2000. The aim of this Conference was to concentrate mainly on recent advances made in the investigation of the relationship between microstructures of materials and their mechanical behaviour; including, fundamentals, modelling and applications. Encompassed in the Conference's aim is the nurturing of the synergistic effect between the theoretical and applied areas in this field. This was achieved by addressing important basic and practical aspects of the mechanical behaviour and damage of materials whilst also providing significant links between various complementary approaches. All kinds of materials are covered and topics that were covered include the mechanics of solid polymers, microstructurs and micromechanisms, and the collective behavior of defects which looks at the interaction of multiple defects in a system.
