Characteristics of viscoelastic resin for a vibration damping composite steel sheet (VDCS) were studied numerically using the Ross-Kerwin-Ungar model. The following three conclusions were obtained : i ) magnitude of shear modulus of the resin determines frequency where the VDCS shows the maximum loss factor ; ii ) although there is a limitation of loss factor, the magnitude of loss factor is proportional to tangential loss of the resin ; and iii) loss factor is independent of frequency if the shear modulus of the resin is proportional to frequency. Characteristics of an actual resin for VDCS were shown to agree with the calculated results. The same trends were observed for the calculated results as for the characteristics of the actual resin. Therefore, the results obtained might be useful in the developement of new resin for VDCS. The results obtained are also useful for understanding the behavior of loss factor in terms of frequency dependence and temperature dependence.
