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 • More emphasis on the environmental impact of engineering products, recycling, and increasing use of biodegradable polymers and composites. • More emphasis on weight reduction of products through design changes as well as material and process selection, especially in the manufacture of electric cars • New methods of 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
