A FAMILY OF MODAL METHODS FOR COMPUTING eigenvector derivativeS WITH REPEATED ROOTS
收藏 引用
Acta Mechanica Sinica 1996年 第2期12卷 158-168页
作者: 王文亮 Dept.of Appl.Mech. Fudan UniversityShanghai 200433China
A family of modal methods for computing eigenvector derivatives with repeated roots are directly derived from the constraint generalized inverse technique which is originally formulated by Wang and Hu. Extensions are ... 详细信息
