Element Method

The finite element method is a numerical method that is used to find solution of mathematical and engineering problems. It basically deals with partial differential equations. It is very complex for civil engineers to study various structures by using analytical method,so they prefer finite element methods over the analytical methods. As it is an approximate solution, therefore several limitationsare associated in the applicationsin civil engineering due to misinterpretationof analyst. Hence, the main aim of the paper is to study the finite element method in details along with the benefits and limitations of using this method in analysis of building components like beams, frames, trusses, slabs etc.

Perforated panels are one of the structures that are widely used nowadays. The sound absorption behavior of materials is studied by solving the equations governing the wave propagation in these materials. In this paper, the finite element method (FEM) was used to predict the absorption performances of few different perforated composite panels. Also, the studied structures were examined by two-microphone impedance tube to validate the results of the numerical method. The relative consistency of the results of the current method with the results of the impedance tube suggests the accuracy of this method in simulating the absorption rate of perforated composites. In addition, the results of evaluating various layouts (arrangements) showed that the use of absorber materials with higher flow resistivity at the back of the perforated panel and at the beginning of the sound wave entry increases the absorption performance by 1.6 times than that of the inverse layout ratio.
