Cold and Hot Forging: Fundamentals and Applications is a practical guide to the design and optimization of forging operations and dies. It reviews relevant engineering principles, describing the deformation and flow of materials, the concept of flow stress, and the development and use of flow rules based on Tresca and von Mises criteria. It discusses the issue of heat generation and transfer along with related factors such as die geometry, materials of construction, press speed, contact time, friction, lubrication, and forging temperature.
