Abstract
This paper presents an examination of the methods for the iterative modal perturbation and the application of these methods to the reanalysis of the eigenvalue problem. The iteration is based on the first‐order modal perturbation. In two examples, it is shown that the iterative analysis has the advantage of accuracy over the addition of higher‐order perturbations and it is an appropriate approach for the reanalysis of the eigenvalue problem in terms of accuracy and computational efficiency.
