Study on energy dissipation pattern in vibrating fluid filled cylindrical shells with a constrained viscoelastic layer

The modal strain energy method is used to study the energy dissipation patt ern in vibrating cylindrical Shells with a viscoelastic damping layer, for various circumferential and axial modes. The effect of tank size, boundary condition and height of contained fluid on the distribution pattern is also investigated. The regions of energy dissipation concentration are identifi ed. The effect of redistribution of the (initially uniformly distributed) c onstrained viscoelastic material by concentrating it in the above regions i s studied. (C) 2000 Elsevier Science Ltd.
