WebA total wave formulation (see “ Coupled acoustic-structural medium analysis, ” Section 2.9.1) is used in Abaqus/Explicit to handle the incident wave loads on an acoustic medium … Web11.8 Transmission of obliquely incident plane waves through an unbounded double-leaf partition So far, only normally incident sound has been considered. When a plane wave is incident at an oblique angle ϕ upon leaf 1 it sets up a bending wave travelling in the plane of the leaf with trace wavenumber kz = k sin ϕ.
