| A new procedure for eigensolution reanalysis has been developed in this thesis. This new method is based on the sensitivity data. Methods for computing eigensolution sensitivity using both exact and approximate methods have been known for a long time. While eigenvalue sensitivity is used routinely in structural optimization with eigenvalue constraints, few applications of eigenvector derivatives are reported.;In this thesis, effective eigensolution reanalysis using first and second order eigenvector sensitivity data is presented. The proposed approach and other eigensolution reanalysis approaches are implemented in Matlab R2008a to get eignesolution of modified design. These results obtained by reanalysis techniques are compared with the exact analysis of modified eigensolution. |
