[资源] 金属成型：力学及冶金（英文第四版）

Metal Forming: Mechanics and Metallurgy, 4th Edition

Author(s): William F. Hosford, Robert M. Caddell
Publisher: Cambridge University Press
Year: 2011
Edition: 4
Language: English
Pages: 345
This book helps the engineer understand the principles of metal forming and analyze forming problems--both the mechanics of forming processes and how the properties of metals interact with the processes. In this third edition, an entire chapter has been devoted to forming limit diagrams and various aspects of stamping and another on 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.
