Improved modal truncation method for eigensensitivity analysis of asymmetric matrix with repeated eigenvalues
《Applied Mathematics and Mechanics(English Edition)》2014年第4期437-452,共16页张振宇 
supported by the National Natural Science Foundation of China(No.11101149);the Basic Academic Discipline Program of Shanghai University of Finance and Economics(No.2013950575)
An improved modal truncation method with arbitrarily high order accuracy is developed for calculating the second- and third-order eigenvalue derivatives and the first- and second-order eigenvector derivatives of an as...
