Mechanical Properties of Materials

The subject of mechanical behavior has been in the front line of basic studies in engineering curricula. This text book was written for engineering students with the aim of presenting the basic concepts of mechanical behavior in solid materials in a relatively simple manner. A second aim of the book is to guide students in their laboratory experiments by helping them to understand their observations in parallel with the lectures of the course taught; therefore the first chapter of the book is devoted to mechanical testing. Another aim of the book is to provide practicing engineers with basic help to bridge the gap of time that has passed from their graduation up to their actual involvement in engineering work. The book also serves as the basis for more advanced studies and seminars when pursuing courses on a graduate level. The content of this text book and the topics discussed correspond to courses that are usually taught in universities and colleges all over the world, but with a different and more modern approach. It is, however, unique by the inclusion of an extensive chapter on mechanical behavior in the micron and submicron/nanometer range which is not provided by traditional textbooks. Mechanical deformation phenomena are explained and often related to the presence of dislocations in the structure. Some important mathematical expression are derived not only stated as in traditional textbooks Many practical illustrations are provided representing various observations encountered in actual structures of technical importance. A comprehensive list of references at each chapter is included to provide a broad basis for further studying the subject.
