Conference paper

Optimal design of lossy bandgap structures

In Procedings of 21st International Congress on Theoretical and Applied Mechanics Ictam Xxi — 2004

The method of topology optimization is used to design structures for wave propagation with one lossy material component. Optimized designs for scalar elastic waves are presented for mininimum wave transmission as well as for maximum wave energy dissipation. The structures that are obtained are of the 1D or 2D bandgap type depending on the objective and the material parameters.
