Materials Selection And Design

This book presents topics on the basics of materials selection and design which will give a better understanding on the selection methods and then find suitable materials for the applications. This book draws the simple and straightforward quantitative methods followed by knowledge-based expert system approach with real and tangible case studies to show how undergraduate or post-graduate students or engineers can apply their knowledge on materials selection and design. Topics discussed in this book contain special features such as illustration, tables and tutorial questions for easy understanding. A few published books or documents are available, hence this book will be very useful for those who use (or want to use) materials selection approach without the advantages of having had comprehensive knowledge or expertise in this materials’ world.

New materials enable advances in engineering design. This book describes a procedure for material selection in mechanical design, allowing the most suitable materials for a given application to be identified from the full range of materials and section shapes available. A novel approach is adopted not found elsewhere. Materials are introduced through their properties; materials selection charts (a new development) capture the important features of all materials, allowing rapid retrieval of information and application of selection techniques. Merit indices, combined with charts, allow optimisation of the materials selection process. Sources of material property data are reviewed and approaches to their use are given. Material processing and its influence on the design are discussed. The book closes with chapters on aesthetics and industrial design. Case studies are developed as a method of illustrating the procedure and as a way of developing the ideas further.

Providing an analytical approach to selecting the best metal and obtaining optimal properties for and in a fabricated part, this text correlates weldability, formability and machinability with a metal's chemical composition through microstructures. It begins with a review of the principles of materials science and offers useful features, such as end-of-chapter problems and a solutions manual.

Materials are the stuff of design. From the very beginning of human history, materials have been taken from the natural world and shaped, modified, and adapted for everything from primitive tools to modern electronics. This renowned book by noted materials engineering author Mike Ashby and Industrial designer, Kara Johnson, explores the role of materials and materials processing in product design, with a particular emphasis on creating both desired aesthetics and functionality. The new edition will feature even more of the highly useful "materials profiles," that give critical design, processing, performance and applications criteria for each material in question. The reader will find information ranging from the generic and commercial names of each material, its physical and mechanical properties, its chemical properties, its common uses, how it is typically made and processed, and even its average price. And with improved photographs and drawings, the reader will be taken even more closely to the way real design is done by real designers, selecting the optimum materials for a successful product. * The best guide ever published on the on the role of materials, past and present, in product development, by noted materials authority Mike Ashby and professional designer Kara Johnson--now with even better photos and drawings on the Design Process * Significant new section on the use of re-cycled materials in products, and the importance of sustainable design for manufactured goods and services * Enhanced materials profiles, with addition of new materials types like nanomaterials, advanced plastics and bio-based materials

Introducing readers to the methodology of engineering design, the book shows how materials selection comes into play during the design of a component or a structure, and examines such engineering requirements as stress, mode of loading, corrosion, and performance efficiencies of materials. Readers are acquainted with the factors of costs and statuatory requirements, including environmental regulations and recycling, and case studies are integrated throughout to illustrate the selection process.

Introducing a new engineering product or changing an existing model involves developing designs, reaching economic decisions, selecting materials, choosing manufacturing processes, and assessing environmental impact. These activities are interdependent and should not be performed in isolation from each other. This is because the materials and processes used in making a product can have a major influence on its design, cost, and performance in service. This Fourth Edition of the best-selling Materials and Process Selection for Engineering Design takes all of this into account and has been comprehensively revised to reflect the many advances in the fields of materials and manufacturing, including: Increasing use of additive manufacturing technology, especially in biomedical, aerospace and automotive applications Emphasizing the environmental impact of engineering products, recycling, and increasing use of biodegradable polymers and composites Analyzing further into weight reduction of products through design changes as well as material and process selection, especially in manufacturing products such as electric cars Discussing new methods for solving multi-criteria decision-making problems, including multi-component material selection as well as concurrent and geometry-dependent selection of materials and joining technology Increasing use of MATLAB by engineering students in solving problems This textbook features the following pedagogical tools: New and updated practical case studies from industry A variety of suggested topics and background information for in-class group work Ideas and background information for reflection papers so readers can think critically about the material they have read, give their interpretation of the issues under discussion and the lessons learned, and then propose a way forward Open-book exercises and questions at the end of each chapter where readers are evaluated on how they use the material, rather than how well they recall it, in addition to the traditional review questions Includes a solutions manual and PowerPoint lecture materials for adopting professors Aimed at students in mechanical, manufacturing, and materials engineering, as well as professionals in these fields, this book provides the practical know-how in order to choose the right materials and processes for development of new or enhanced products.

The selection of the proper materials for a structural component is a critical activity that is governed by many, often conflicting factors. Incorporating materials expert systems into CAD/CAM operations could assist designers by suggesting potential manufacturing processes for particular products to facilitate concurrent engineering, recommending various materials for a specific part based on a given set of characteristics, or proposing possible modifications of a design if suitable materials for a particular part do not exist. This book reviews the structural design process, determines the elements, and capabilities required for a materials selection expert system to assist design engineers, and recommends the areas of expert system and materials modeling research and development required to devise a materials-specific design system.

Multi-criteria Decision Analysis for Supporting the Selection of Engineering Materials in Product Design, Second Edition, provides readers with tactics they can use to optimally select materials to satisfy complex design problems when they are faced with the vast range of materials available. Current approaches to materials selection range from the use of intuition and experience, to more formalized computer-based methods, such as electronic databases with search engines to facilitate the materials selection process. Recently, multi-criteria decision-making (MCDM) methods have been applied to materials selection, demonstrating significant capability for tackling complex design problems. This book describes the rapidly growing field of MCDM and its application to materials selection. It aids readers in producing successful designs by improving the decision-making process. This new edition updates and expands previous key topics, including new chapters on materials selection in the context of design problem-solving and multiple objective decision-making, also presenting a significant amount of additional case studies that will aid in the learning process. Describes the advantages of Quality Function Deployment (QFD) in the materials selection process through different case studies Presents a methodology for multi-objective material design optimization that employs Design of Experiments coupled with Finite Element Analysis Supplements existing quantitative methods of materials selection by allowing simultaneous consideration of design attributes, component configurations, and types of material Provides a case study for simultaneous materials selection and geometrical optimization processes
