Master's Thesis from the year 1998 in the subject Engineering - Communication Technology, Virginia State University (Unbekannt), language: English, abstract: Inhaltsangabe: Abstract: This thesis studied the finite element modeling of plane wave acoustic phenomena in ducts. The study looked into finite element factors such as shape functions, mesh refinement, and element distortion. The study concluded that the higher order shape function eight-node quadrilateral element gave considerably better results than lower order shape function four-node quadrilateral element. The eight-node element...
