Friction is a complex system affected by microscopical effects and multidisciplinary
phenomena. Coulomb's simple friction model with a constant friction coefficient cannot …

The paper presents the results of a study of the process of axial rotary forging by a conical
roll performing a complex movement. In addition to the usual rotational motion the forming …

In this paper, the virtual atomic force microscope (AFM) is constructed on the basis of the
component models to simulate the conventional and high-speed AFMs. A room temperature …

The oscillations of a circular cylindrical shell of finite length with additional inertia mass are
explored. The shell contacts with an elastic medium, which reaction is represented by …

Research on bridge construction elements was conducted as part of a joint project by the
Cracow University of Technology and PKP Polish Railway Lines, funded by the NCBiR. In …
