Abstract: The finite element method has been used to predict the structural intensity of a plate with multiple discrete and distributed dampers. Different combinations of dampers in different positions were employed to study the effects of multiple dampers in an individual plate model to examine the energy flow phenomenon in the presence of many dissipative elements. The structural intensity of plate structures connected by loosened bolts subjected to forced excitation is also presented in this paper. The loosened bolts are modelled by discrete as well as distributed spring-dashpot systems. The distributed springs and dampers are introduced to characterize the joint behavior of the plates. Numerical results are also presented for the plates connected by two bolts. © 2003 Elsevier Ltd. All rights reserved.
