For achieving realistic numerical simulations of bowed string instruments, based on physical modeling, a good understanding of the actual friction interaction phenomena is of great importance. Most work published in the field including our own has assumed that bow/string frictional forces behave according to the classical Coulomb stick–slip model, with an empirical velocity-dependent sliding friction...
Some mechanical components of PWR nuclear power plants can be sensitive to wear damage resulting from contacts with their supports or guides due to flow-induced vibrations. It is particularly the case of the control rods (rod cluster control assemblies (RCCAs)) and RCC guide tubes inside the reactor pressure vessel. In order to improve our knowledge about the wear behavior of such components, an extensive...
