摘要：
Boundary element method accelerated by the precorrected-FFT algorithm is developed and implemented for 3-D frequency-domain elastodynamic problems. Some critical implementation issues are described. The accuracy and efficiency of the developed method are validated via the comparison between the simulated results and analytical solutions or FEM results of three examples. Excellent agreements are demonstrated in all three examples. (C) 2010 Elsevier Ltd. All rights reserved.
