tailieunhanh - Mechanical Properties of Engineered Materials P1

The mechanical behavior of materials describes the response of materials to mechanical loads or deformation. The response can be understood in terms of the basic effects of mechanical loads on defects or atomic motion. A simple understanding of atomic and defect structure is, therefore, an essential prerequisite to the development of a fundamental understanding of the mechanical behavior of materials. | Mechanical Properties of Engineered Materials Wolé Soboyejo Princeton University Princeton New Jersey MARCEL DEKKER Marcel Dekker Inc.

Preface My primary objective in this book is to provide a simple introduction to the subject of mechanical properties of engineered materials for undergraduate and graduate students. I have been encouraged in this task by my students and many practicing engineers with a strong interest in the mechanical properties of materials and I hope that this book will satisfy their needs. I have endeavored to cover only the topics that I consider central to the development of a basic understanding of the mechanical properties of materials. It is not intended to be a comprehensive review of all the different aspects of mechanical properties such a task would be beyond the capabilities of any single author. Instead this book emphasizes the fundamental concepts that must be mastered by any undergraduate .
