Abstract

Abstract

In this paper,a new technique of state vector approach to solving damping ratios of adaptive structures is proposed,by which the state matrix can be analytically conducted the Cholesky decomposition,providing that the mass matrix is derived by lumped method.In this case,not only the computational accuracy is raised,but also the numerical operations are reduced.Finally,some numerical results are presented to show that the solution method is simple and efficient.
