Acoustics Willis media, known as bianisotropic acoustic incorporate additional coupling between pressure and velocity momentum volumetric strain in their constitutive equation. The extra terms have a significant influence on wave behavior. In this paper, the unusual phenomena relevant to interfaces homogeneous media are theoretically studied. We show that offer more flexible control front energ...

confined masonry buildings are used in rural and urban areas of iran. they performed almost satisfactoryduring past moderate earthquakes of iran. there is not a methodology in iranian seismic code (standard 2800-3rdedition) to estimate their capacities quantitatively. in line with removing this constraint, an attempt is made to studyin-plane behavior of two squared confined masonry walls with a...
