The author discusses the change in the damping type in SDOF system from viscous to material one. This is valid both for modal and spectral methods. The main advantage is clear “physical sense” of the damping model both for homogeneous systems and for “composite” systems. However, the procedure to obtain time-domain responses for material damping is slightly more complicated, as it is performed via frequency domain.
