Finite element optimisation of designed-in viscoelastic damping pockets in beams

Research output: Chapter in Book/Conference proceeding › Conference contribution › peer-review

Abstract

In this work, a designed-in damping treatment is applied to a simple cantilevered beam. The geometric parameters of this designed-in damper are then optimised to achieve maximum levels of damping but minimum effect on the structural stiffness of the beam. It is shown that the effectiveness of the damping pockets depends on their location and size with respect to the highly stressed regions of the beams. If located correctly, they are more effective than a traditional CLD treatment.
