An O(N) Taylor series multipole boundary element method for three-dimensional elasticity problems

Abstract It has been previously reported in the open literature that multipole boundary element strategy based on Taylor expansions can result in computer codes which require O(N log N) operations for problems with N degrees of freedom. In this work we present a multipole BEM strategy developed for three-dimensional elasticity problems which is also based on Taylor expansions but requires only O(N) operations and O(N) memory. Results are presented for size of problems in which N=O(104).
