Abstract

In processes of metal formation at an elevated temperature, the fracture criterion should depend at least on the parameter of a triaxial stressed state, the equivalent strain rate, and the temperature. This significantly complicates the investigation in comparison with the case of cold processing. However, in the case of fracture initiation at the free surface under plane-strain conditions, a computational scheme is found that is similar to the one used in processes of cold working under pressure, although in another space. This scheme is used for the prediction of the beginning of the fracture in the process of the simultaneous bending and straining of a wide bar.
