A working understanding of materials principles is essential in every area of engineering. However, the materials requirements of different engineering disciplines can vary considerably. Existing introductory textbooks on engineering materials adopt a universalist approach, providing theoretical development and surveying a landscape of topics suitable for introducing materials engineers to their field. Materials for Engineers: Principles and Applications for Non-Majors has been constructed with the requirements of non-materials engineering students (“non-majors") in mind. The theoretical foundations of material structure and behavior are curated and focused, and the description of the behavior of materials as they pertain to performance, measurement, and design are developed in detail. The book: Places applications and essential measurement methods before detailed theory Features a variety of types end-of-chapter exercises, including forum discussion topics for online course components Emphasizes computer-based problem solving and includes numerous examples and exercises for MATLAB® Includes optional “topic” chapters for course customization, including structures, transportation, and electronics Outlines practical details of how and why knowledge of materials is necessary for engineers, including the various roles that materials engineers play and the impact of materials on cost, lifespan, and safety of components and products This textbook is aimed at undergraduate engineering students taking their first materials engineering course. It can also be used by professional engineers interested in a ready reference. A solutions manual, lecture slides, and example data sets are available for adopting professors.
