An FFT-Based Spectral Analysis Method for Linear Discrete Dynamic Systems with Non-Proportional Damping

This paper proposes a fast Fourier transforms (FFT)-based spectral analysis method for the dynamic analysis of linear discrete dynamic systems which have non-proportional viscous damping and are subjected to non-zero initial conditions. To evaluate the proposed FFT-based spectral analysis method, th...
