During the last 20 years, the development of experimental modal analysis techniques has facilitated the accurate measurement of modal parameters in many types of structure. Alongside this work, several methods have been developed to detect structural damage by using location-dependent changes in the
The dynamic behavior of a printed wiring (PW) board plays an important role in its reliability. One key parameter in determining such behavior is the fundamental frequency of the PW board. This paper shows how the sensitivity of the natural frequencies of the board with respect to some design variab
The sensitivity of eigenvalues to the location of bracing and/or boundary support is formulated by using a generalized variational principle. The constraints are incorporated through the use of Lagrange multipliers. A numerical example is provided to illustrate the proposed method and its accuracy i
