A sequential upper bound method for the cylindrical compression test is developed. The method uses rigid and plastic regions to build up a kinematically admissible velocity field. A technique for calculating the power dissipation in continued compres

The paper presents a simple and efficient method for identifying two-parametric isotropic pressure-independent yield criteria. The experimental procedure includes the upsetting of three types of specimens. The upsetting of cylinders and rings is used

This paper aims to develop a method for determining the workability diagram by varying frictional conditions in the cylinder upsetting test. The method is based on a known theoretical relationship between the average stress triaxiality ratio and in-s

Compared to conventional metal forming methods, processing by severe plastic deformation is mostly used to improve the mechanical properties and not for the shaping of a product. Processed material usually has an average crystal grain size of less th

Severe plastic deformation (SPD) processes are widely used for improving material properties. A distinguishing feature of many SPD processes is that the principal axes of the stress tensor intensively rotate relative to the material. Nevertheless, no

The ring compression test is a conventional test for identifying the friction law for metal forming applications. This test is very widely used but has a significant disadvantage. In particular, if the friction stress is high, then a sticking region
