Summary: | In this study, the influence of the clamped-free beam specimen length on the measured fundamental vibration frequencies of flat sandwich beams is investigated. First, sandwich beams having flat galvanized steel faces, and a rigid foam core are produced, and clamped beam vibration tests are conducted on specimens having three different lengths. The experimental results obtained are compared with the numerical results obtained using a 1D finite element model. The results obtained show that the clamped beam vibration test yields satisfactory results,
and the longer specimens yield more accurate results. |
