VIBRATION MECHANICS B
Learning outcomes of the course unit
The course gives the basics for the theoretical and experimental vibration analysis of continuous systems.
Course contents summary
Vibrations of continuous systems: local and global discretization (Rayleigh-Ritz, Galerkin, FEM); vibrations of beams and thin-walled structures.
Introduction to large-amplitude vibrations and nonlinear phenomena.
Stability problems of systems with fluid-structure interaction: flutter and divergence of aeronautical and aerospace structures.
Applications to actual problems.
Experimental modal analysis on structures with high modal density.
