The sandwich specimens comprise DC01 mild steel plates and steel foam hollow spheres bonded together with a thermosetting epoxy. Specimens included single-phase steel foam core sandwich specimens and two-phase specimens with semi-filled steel foam cores with different volumes of lubricant oil. Three different tests were performed, specifically sine sweep over a range of frequencies, white noise and shock. The results show very good correlations in the estimation of the harmonic frequencies and promising damping ratios for the single-phase cores with further improvements in the presence of two-phase cores. | URI: | https://hdl.handle.net/20.500.14279/21110 | Rights: | CC0 1.0 Universal | Type: | Report | Affiliation : | Cyprus University of Technology Cranfield University University of Strathclyde |
