Modeling and Eigenfrequency Analysis of Sound-Structure Interaction in a Rectangular Enclosure with Finite Element Method

A 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...

Sound equalization in a large region of a rectangular enclosure.

A 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...

Three-dimensional numerical modeling of score hole in rectangular side weir with finite volume method

Local scouring in the downstream of hydraulic structures is one of the important issues in river and hydraulic engineering, which involves a lot of costs every year, so the prediction of the rate of scour is important in hydraulic design. Side weirs are the most important of hydraulic structures that are used in passing flow. This study investigate the scouring due to falling jet from side weir...

The Finite Element Method with the Dirichlet-to-Neumann Map for Sound-Hard Rectangular Rooms

In this paper, the finite element method (FEM) is used to solve the Helmholtz equation for a rectangular room with sound-hard boundaries. An imaginary surface is introduced to truncate the room, reducing the effective room size and thus the computational costs. The boundary condition on the imaginary surface is the Dirichletto-Neumann (DtN) map that exactly models the effect of the portion of t...
