An asymptotic theory of resonance interaction of shear and bending modes in a non-uniform Timoshenko beam

The propagation of modes in a smoothly non-uniform Timoshenko beam is considered. We present an asymptotic theory of interaction of two modes whose phase velocities intersect at a single point and are non-tangent there. The high-frequency regime in the time-harmonic case and propagation of discontinuities are both considered.
