Similar Boundary Element Method in Elastodynamics[J]. Journal of Civil and Environmental Engineering, 2000, 22(6): 1-4. DOI: 10.11835/j.issn.1674-4764.2000.06.001.
some properties of matrices are discussed in case of similar boundary elements and the similar boundary element method is presented. In a series of similar boundary elements
when the corresponding matrices of a boundary element are obtained
the ones of other boundary elements in the series can be obtained by proportion. Then the coefficient matrix of the last system of linear algebraic equations can be obtained by the method of superposition. Compared with the general boundary element method
the computing speed can be raised by the similar boundary element method given in this paper.
