This book is designed to help the engineer understand the principles of metal form￾ing and to analyze forming problems – both the mechanics of forming processes and how the properties of metals interact with the processes. In this book, an entire chapter is devoted to forming limit diagrams and various aspects of stamping and another to other sheet forming operations. Sheet testing is covered in a separate chapter. Coverage of sheet metal properties has been expanded. Interesting end￾of-chapter notes have been added throughout, as well as references. More than 200 end-of-chapter problems are also included
