Shape Optimization of Shell Structure Acoustics
SM1. Introduction. This supplement contains details that were omitted from the main paper [SM2] because of page limitations. SM2. The Model for the Shell Structure Acoustic Interaction. To avoid switching between the main paper and this supplement, we have included the entire expanded version of Section 2, not only the details and proofs missing from Section 2 of the main paper. SM2.1. Naghdi S...
متن کاملShape conforming volumetric interpolation with interior distances
Source based heterogeneous modelling is a powerful way of defining gradient materials within a volume. The current solutions do not take into account the topology of the object and can provide counter intuitive results for complex objects. This paper presents a method to interpolate material properties and attributes based on the accessibility of the points in respect to the material features d...
متن کاملShape Optimization of Cylindrical Shell for Interior Noise
In this paper an analytic method is used to solve for the cross spectral density of the interior acoustic response of a cylinder with nonuniform thickness subjected to turbulent boundary layer excitation. The cylinder is of honeycomb core construction with the thickness of the core material expressed as a cosine series in the circumferential direction. The coe cients of this series are used as ...
متن کاملThe use of radial basis functions by variable shape parameter for solving partial differential equations
In this paper, some meshless methods based on the local Newton basis functions are used to solve some time dependent partial differential equations. For stability reasons, used variably scaled radial kernels for constructing Newton basis functions. In continuation, with considering presented basis functions as trial functions, approximated solution functions in the event of spatial variable wit...
متن کاملWave based modelling methods for steady-state interior acoustics: an overview
This paper discusses the use of wave based prediction methods for the analysis of steady-state interior acoustic problems. Conventional element based prediction methods, such as the Finite Element Method (FEM), are commonly used, but are restricted to low-frequency applications. The Wave Based Method (WBM) is an alternative deterministic technique which is based on the indirect Trefftz approach...
