Ray and wave scattering in smoothly curved thin shell cylindrical ridges
Niels Sondergaard, David Chappell
We propose wave and ray approaches for modelling mid- and high- frequency structural vibrations through smoothed joints on thin shell cylindrical ridges. The models both emerge fro…

Transport of phase space densities through tetrahedral meshes using discrete flow mapping
Janis Bajars, David Chappell, Niels Sondergaard +1
Discrete flow mapping was recently introduced as an efficient ray based method determining wave energy distributions in complex built up structures. Wave energy densities are trans…

On sparse reconstructions in near-field acoustic holography using the method of superposition
Nadia M. Abusag, David J. Chappell
The method of superposition is proposed in combination with a sparse optimisation algorithm with the aim of finding a sparse basis to accurately reconstruct the structural…
