Abstract:
Equations of axially symmmetric motion are derived for a cylindrical shell whose two layers are connected by a thin, deformable bond. Effects of shear deformation and rotatory inertia are accounted for in each of the shell layers. A thin, inertialess, interlayer bond that deforms only in shear is assumed. A nondimensional bond stiffness parameter is introduced, and the effect of bond stiffness on the dynamic behavior of the shell is investigated for the case of axial wave propagation in an infinitely long shell. The bond stiffness parameter has a profound influence on some of the wave propagation frequencies. An expression is given for a critical value of the bond stiffness parameter that separates stiff and soft bonds. For the limiting cases of very stiff or very soft bonds, simplified theoretical approaches give adequate accuracy however, it appears necessary to use the theory in full for bonds of intermediate thickness.
