Paper Title:
Modal Decomposition Solution of Lamb Wave Scattering at Step-Like Discontinuity
  Abstract

Modal decomposition method is utilized to investigate Lamb wave scattering at step-like discontinuity. The structure is regard as a special delamination structure where one or two delamination layers are missing and only one delamination layer extended to infinite. Model decomposition technique is then combined with the boundary condition equations to get the scattering solution of the whole discontinuity region. The efficacy of the method is illustrated by calculation examples where the scattering of the second symmetric mode at step-discontinuity with different thickness are evaluated and Energy flux conservation is confirmed.
