7. Conclusion The intent of this article is to answer the two basic questions asked by the title: what to know about finite element modeling techniques andwhere to apply them in themetal forming and forging industries. After a concise introduction of the history, classification and benefits of metal forming, the fundamental theories of metal forming and the important aspects of building effective finite element models are briefly reviewed. The knowledge areas and skills that a design or process engineer who conducts finite element analyses needs are outlined. In the last section, the author offers a few examples of real- world applications of finite element analysis, from which the reader can sense how it can be used both in tooling or process development and in troubleshooting product defects or process problems. ■ 8.
