Some Problems in Modelling of the Fast Deformation of Metals
We have developed a technological and mathematical model for the fast deformation of metals, which, as a result of the non-linear nature of the process, is equally suitable for the description of stable (continuous or periodic) and also chaotic states. In the case of stable solutions, the various numerical methods generally give consistent results, but in chaotic cases significant differences can be observed in the space of state characteristics, especially within the range determined by the strange attractor.
