EnglishThe article addresses the elastodynamic behaviour of a 'shear-type structured' interface separating two elastic regions. The structure includes a system of horizontal elastic bars connected by transverse massless elastic links. For a plane wave transmission problem, the analytical results obtained here show that such an interface acts as a 'shear polariser'. A special attention is paid to the analysis of the defect modes (also referred to as resonance modes) within the interface. It is shown that these vibration modes induce enhanced transmission within the elastic system.

| Abstract: | The article addresses the elastodynamic behaviour of a 'shear-type structured' interface separating two elastic regions. The structure includes a system of horizontal elastic bars connected by transverse massless elastic links. For a plane wave transmission problem, the analytical results obtained here show that such an interface acts as a 'shear polariser'. A special attention is paid to the analysis of the defect modes (also referred to as resonance modes) within the interface. It is shown that these vibration modes induce enhanced transmission within the elastic system. |
