LOCALISED DEFECT MODES AND A MACRO-CELL ANALYSIS FOR DYNAMIC LATTICE STRUCTURES WITH DEFECTS
- 1.3k Downloads
This paper presents an analysis of inertial lattice structures with periodically distributed defects. Such structures exhibit stop bands for certain ranges of frequencies, prohibiting propagation of waves of such frequencies through the structure. In the engineering literature, structures of this type are referred to as “passive mass dampers”.
