ON THE DISPERSION OF TORSIONAL WAVES IN THE IMPERFECTLY BONDED FINITELY PRE-STRAINED BI-MATERIAL HOLLOW CYLINDER MADE OF HIGHLY-ELASTIC MATERIAL

Abstract

In this paper, the influence of the bonded imperfectness on torsional wave dispersion in the finitely pre-strained hollow bi-material compound circular cylinder made of highly-elastic material were investigated. The investigations are carried out within the scope of the piecewise homogeneous body model with the use of the Three-dimensional Linearized Theory of Elastic Waves in Initially Stresses Bodies. The mechanical relations of the materials of the cylinders are described through the harmonic potential. Numerical results on the effects of the imperfectness of the boundary condition on the influence of the initial stresses on the wave propagation velocity are presented and discussed.
