Abstract

Condensation algorithms have been used to calculate the eigensolutions of structures. Some iterated dynamic condensation methods, especially iterated IRS (IIRS), have been developed to improve the efficiency of this kind of method. Two acceleration techniques, Aitken's extrapolation and shift, are presented in this paper to make the IIRS converges faster to the accurate results. The two strategies are applied to two numerical results to illustrate the procedure and effectiveness. Some problems, such as computation cost, are discussed.
