Micro Abstract:
The use of correct damping parameters is a decisive aspect in the numerical simulation of dynamical problems and indispensable to predict and reduce reliably vibration amplitudes. In this contribution, experimental and numerical studies to identify damping coefficients of simple geometries are presented. In the experiments the focus was set to measure the pure material damping excluding all disturbing environmental influences. In the numerical investigation, the thermoelastic approach was used.
