Abstract

Existence criteria and basic characteristics are analytically found for elastic waves localized at a twist boundary in transverse isotropic media. The boundary is formed by two identical semi-infinite bodies with non-collinear principal axes parallel to the interface. The analysis is based on the Stroh formalism specified to the case of transverse isotropy. The dispersion equation is presented in a general form and explicitly solved for small misorientations. The waves in the sector situated between the directions of transverse isotropy in the sub-media of the bicrystal are explicitly described.
