Eigenvalue and eigenvector derivatives with respect to system design variables and their
applications have been and continue to be one of the core issues in the design, control and …

Since Lord Rayleigh introduced the idea of viscous dam** in his classic work" The Theory
of Sound" in 1877, it has become standard practice to use this approach in dynamics …

In paper the design sensitivity analysis of dynamic characteristics of structures with
viscoelastic (VE) dampers is considered. The dampers are modeled using the classical …

In this paper, a novel algorithm for computing the derivatives of eigensolutions of asymmetric
damped systems with distinct and repeated eigenvalues is developed without using second …

A generalized eigenproblem is formed and its normalizations are presented and discussed.
Then a unified consideration of the computation of the sensitivity and Hessian matrix is …

By extending the existing scaled boundary finite element method (SBFEM) into the random
field problem, a stochastic scaled boundary finite element method (SSBFEM) is developed …

Calculation of eigensensitivity is usually time-consuming for a large-scale structure. This
paper develops a substructuring method for computing the first, second and high order …

Calculation of the first and second derivatives of transient response with respect to design
variables is a prerequisite when gradient-based methods are adopted for optimization …

Various methods for the calculation of the sensitivity of element modal strain energy (MSE)
are surveyed and classified as the finite difference method, the indirect method and the …

This paper presents a new algorithm for computing the sensitivity of eigenpairs in
asymmetric damped systems with repeated eigenvalues. The derivatives of eigenvectors in …
