Résumé

This paper considers the vibration of a cantilever beam with a thick layer of viscoelastic damping material bonded to one surface. The measured forced response is compared to numerical results obtained using the VAST direct frequency response method in conjunction with measured dynamic mechanical properties for the damping material. Predictions of the composite system loss factor, made using VAST and independently using a code PREDC, are also compared to the experimental data. PREDC is a computer program obtained from University of Dayton, Ohio which employs analytical equations for free and constrained damping treatments of beams and rectangular plates
