Finite Element Study of Plane Wave Acoustic Phenomena in Ducts
… around 30 % for a mesh refinement of about 14 elements per wavelength at 100 Hz frequency. The eight-node element in the other hand had average absolute errors of less than 1% under the same conditions. This section also found that the eight-node element was substantially more resistant to …

Finite Element Modeling of Seismic Wave Propagation in Earthen Embankments
… from external boundaries and numerical dispersion were first examined in the frame work of COMSOL. A combination of an absorbing layer and dashpot elements produced minimal reflections. The numerical dispersion study suggested a mesh composed of 5 quartic (4th order) elements per wavelength …

Experimental and Computational Methods for Investigating Automotive Door Closure Sounds
… to examine the acoustic trends present during operation of an automotive door closure at two impact speeds using experimental and computational methods. The impact speeds were 0.851m/s and 1.179m/s. Transient sound pressure measurements from five different door closure mechanisms were collected …
