Тези доповіді


This work presents an innovative methodology for performing the modal analysis of axially symmetric structures at each time instant. This methodology consists in couplings the eXtended Finite Element Method with the Directional Derivatives. The structures we are interested in result from the removal of material during the boring operation.
