Abstract
A key ingredient in the Hybrid deterministic-statistical approach to the vibroacoustic analysis of complex uncertain structures (Shorter and Langley 2005) is the power absorbing dynamic stiffness matrix. The derivation of such a matrix associated with the flexural motion of a thin, flat, homogeneous plate, based on the cylindrical wave representation of the displacement field over a single convex domain (Lande 2005), is presented here. Key theoretical concepts are discussed, and the numerical results from a simple application are compared against Monte Carlo simulation results.
