Efficient Computation of Eigenvector Sensitivities for Structural Dynamics

An iterative procedure is presented for computing eigenvector sensitivities due to finite element model parameter variations. The present method is a preconditioned conjugate projected gradient-based technique and is intended to utilize the existing matrix factorizations developed for an iterative e...
