## Engineering Design: A Materials and Processing ApproachThis popular engineering design text covers the many factors influencing the design process, including technical, social, and economic considerations. Covered in detail is the topic of "materials selection" (the author's forte). This edition includes, material on computer aided design and new problems and exercises throughout. The text is aimed at the senior level course in design offered in both mechanical and materials science engineering departments. |
