Ryszard B. Pecherski - Viscoplastic Flow in Solids Produced by Shear Banding

Many friends and coworkers supported and helped the author pursue this complex never‐ending story on multiscale deformation mechanisms of different hard deformable metallic solids that I would like to recount, at least partly. As mentioned above, Andrzej Korbel, a Polish Academy of Arts and Sciences member, and Włodzimierz Bochniak became ‘spiritus movens’ of my long‐time activity in this field. It happened due to the help of Mrs Romana Ewa Śliwa, a professor at the Rzeszów University of Technology. She was the first to see my preliminary presentations on localisation phenomena long ago, wisely suggesting contacts with already‐knowledgeable and experienced material science researcher Andrzej Korbel. Then, during many years of my works on shear banding phenomena, it was Zdzisław Nowak, PhD, DSc, who showed me the possibilities of numerical analysis of plastic deformation processes accounting for the shear bands effects and identifying the shear banding contribution function. Also, Katarzyna Kowalczyk – Gajewska, PhD, DSc, gave me a helping hand in the numerical simulations of experimentally realised channel‐die compression and shearing processes. The studies showed a valuable perspective with the significant experience and knowledge of professor Zenon Mróz, a Member of the Polish Academy of Sciences, and Katarzyna Kowalczyk – Gajewska on cyclically loaded tubes on the KOBO processes. I also received a big help from Mrs Aleksandra Manecka – Padaż, MSc, in elaborating the book's graphics. Together with discussions in statu nascendi of the work, her contribution became invaluable. The late professor Piotr Perzyna, my PhD advisor and scientific tutor, contributed to my studies with many valuable discussions about the shear banding model and its applications in the studies of viscoplastic processes.
