Description:


The focus lies on the experimental and numerical investigation of vibrating structures with joints. Here, energy dissipation by microslip effects in the joints is the major source of damping, which is the main quantity of interest. However,the joints are local nonlinearities, which make the application of classical linear modal analysis prohibitive and nonlinear methods have to be used.
