Materials Selection in Mechanical Design, Fourth Edition

Materials influenced lives in Epictetus’ time and continue to do so today. In his day, the number of materials was small; today it is vast. The opportunities for innovation that materials offer now are equally immense. But advance is possible only if a procedure exists for making a rational choice from the materials on this great menu, and—if they are to be used—a way of identifying ways to shape, join, and finish them. This book develops a systematic procedure for selecting materials and processes, leading to the subset that best matches the requirements of a design. It is unique in the way that the information it contains has been structured. The structure gives rapid access to data and allows the user great freedom in exploring potential choices. The method is implemented in software* to provide greater flexibility. All users and modes on the transportation system play important roles in the efficient and effective movement of goods and people. This book focuses on highway infrastructure and the operations of that system, and documents the methodologies and analysis practices for the design, operational analysis, and safety assessment of the system. A fundamental consideration in highway engineering is the human element.
