The finite element method can not only give the external load and the changes in the shape of the workpiece, but also the internal stress and strain distribution. The disadvantage is that the computer time is more, especially when the elastoplastic finite element is used to solve the problem, the computer capacity is larger. The machine time is longer. Recently, there is a trend to adopt a joint approach to analyze problems, for example. The upper limit method is used for rough calculation, and the finite element is used for detailed calculation in key parts.

Reducing friction can not only save energy, but also increase the life of the mold. Since the deformation is relatively uniform, it is helpful to improve the structure and performance of the forging. One of the important measures to reduce friction is to use lubrication. Due to the different forging methods and the difference in working temperature, the lubricants used are also different. Glass lubricants are mostly used for forging of high-temperature alloys and titanium alloys. For hot forging of steel, water-based graphite is a widely used lubricant. For cold forging, due to the high pressure, phosphate or oxalate treatment is often required before forging.
