Figure 5

The dynamic test results of HDBs with different internal configurations. (a) Dynamic stiffness under low frequency band, large amplitude excitations; (b) loss angle under low frequency bands, large amplitude excitations; (c) dynamic stiffness under high frequency band, small amplitude excitations; (d) loss angle under high frequency band, small amplitude excitations.
