Abstract

The present paper extended the acoustical wave propagator technique to investigate the power flow and reflection and transmission coefficients in L-shaped structures consisting of thin and thick plates with rotary inertia and shear deformation effects in the analysis. The general analytical solutions of displacements, reflection and transmission coefficients, and wave intensity of the above structure are given in the time domain. Moreover, the specifically analytical solutions for a given initial wave packet of displacement are derived and compared with those obtained by the acoustical wave propagator technique to verify its validity. This analysis also supplies a theoretical frame to measure experimentally power flow and power loss in coupled plate structures.
