Besides the above theory developments, some new sheet metal forming technologies are reviewed simultaneously. The warm forming technology of Mg alloy is discussed. New processes to form sheet parts and to bend tubes are proposed by using hard granules. On the other hand, a new kind of ultra-...
The intelligent press forming of sheet metal is a completely new and comprehensive technology that combines control-science, computer science, material science and metal forming theory. Although the technology originated in 1980s from America, it was focused on the spring-back of V-shaped bending. ...

A fast and advanced FE analyzing method, the One-step Inverse CAE method, for sheet metal forming is developed and extended to its relative fields, such as progressive die design and its blank shape unfolding, trimming die design and its profile predicti
A monotonic and proportional deformation is usually assumed for the development of a simple theory for sheet forming. The term monotonic implies that the principal strain increments, dε, increase smoothly in a constant direction without any inversion. A process is said to be proportional when the...
