Fast frequency response computation for Rayleigh damping

open access: yes, 2006
We present a model reduction Lanczos method for the computation of frequency response functions of Rayleigh damping problems. The connection with modal extraction and modal superposition is made. The usual model reduction methods require complex arithmetic. With the proposed method, complex arithmetic is only used for the reduced problem.
