Shock and Vibration, Volume 2020, Issue 1, 2020., 2020 Spectral methods have previously been applied to analyze a multitude of vibration and acoustic problems due to their high computational efficiency. However, their application to interior structural acoustics systems has been limited to the analysis of a single plate coupled to a fluid‐filled cavity. In this work, a general multidomain spectral approach

First- and second-order sensitivity analysis schemes by collocation-type Trefftz method
Computer Assisted Methods in Engineering and Science, 2023 This paper presents the boundary-type schemes of the first- and the second-order sensitivity analyses by Trefftz method. In the Trefftz method, physical quantities are approximated by the superposition of the T-complete functions satisfying the ...

Coupling techniques of Trefftz methods
Computer Assisted Methods in Engineering and Science, 2022 The Trefftz method pioneered by Trefftz [71] in 1926 is described as follows: The particular solutions or the fundamental solutions are chosen, a linear combination of those functions is regarded as an approximate solution of partial differential ...

Trefftz polynomials reciprocity based boundary element formulations for elastodynamics
Computer Assisted Methods in Engineering and Science, 2023 In this paper Trefftz polynomials are used for the BEM (Boundary Element Method) based on the reciprocity relations. BEM provides a powerful tool for the calculation of dynamic structural response in the frequency and time domains.
