Abstract:

A review of the developed numerical models for simulation of the bulk metal forming processes that take into account influence of the strain path change on material flow is presented in this paper. The strain patch change effect influences many crucial properties of the deformed material i.e. leads to increase in ductility. That provides a possibility of forming materials, which are difficult to form in a conventional manner. In recent years a lot of experimental and numerical research have been done on development of these new non-conventional bulk forming processes. The main advantages and limitations of the modified forging, extrusion and simple compression tests are summarized and presented in this work. Difficulties in development of the complex rheological model that takes in to account both thermal and structural changes in the deformed material are also discussed.
