PY - 2001/09/01 Y2 - 2024/03/28 TI - Eigenfrequency extraction based on boundary element method JF - Canadian Acoustics JA - Canadian Acoustics VL - 29 IS - 3 SE - Proceedings of the Acoustics Week in Canada DO - UR - https://jcaa.caa-aca.ca/index.php/jcaa/article/view/1373 SP - 30-31 AB - An alternative approach for the extraction of acoustic eigenfrequencies was developed by recasting the nonlinear acoustic eigenvalue problem to a standard eigenvalue form through the linear interpolation of boundary element system matrices. The applicability of the resulting approach was demonstrated by solving example problems and comparing the results to alternative solutions. ER -
