Sound transmission analysis using the hybrid finite element - wave based approach for coupled vibroacoustic problems
In this paper, a hybrid structural finite element (FE) acoustic wave based (WB) approach is formulated to avoid using extra acoustic FE in the case of a simple structural geometry but with complicated structural material properties. Following the formulation, the approach is implemented and validated. First, linear hexahedral solid elements with a selective reduced integration are implemented i...
متن کاملA hybrid finite element approach to modeling sound radiation from circular and rectangular ducts.
A numerical model based on a hybrid finite element method is developed that seeks to join sound pressure fields in interior and exterior regions. The hybrid method is applied to the analysis of sound radiation from open pipes, or ducts, and uses mode matching to couple a finite element discretization of the region surrounding the open end of the duct to wave based modal expansions for adjoining...
متن کاملA Proposed Modeling Method in Finite Element Slope Stability Analysis
Limit-equilibrium method (LEM) and finite element method (FEM) with strength reduction method (SRM) techniques are the most widely used analysis tools in slope stability assessment. Recently, researchers have reported that both factor of safety (FOS) values and failure surfaces obtained from LEM and FEM are generally in good agreement, except in some particular cases. In this paper, the FOS and...
متن کاملA Finite Element Approach to the Prediction of Sound Transmission through Panels with Acoustic Resonators
Previous research by the authors has shown that sound radiated by a vibrating panel can be reduced considerably by using tuned acoustic resonators. The length of the tube resonators determines the frequency range in which sound is reduced. The shape of the spectrum is determined by the ratio of the cross-sectional areas of the resonators to the area of the panel. Maximum sound reduction is achi...
متن کاملA New Stress Based Approach for Nonlinear Finite Element Analysis
This article demonstrates a new approach for nonlinear finite element analysis. The methodology is very suitable and gives very accurate results in linear as well as in nonlinear range of the material behavior. Proposed methodology can be regarded as stress based finite element analysis as it is required to define the stress distribution within the structural body with structural idealization a...
