In this
paper, the free vibration analyses of aluminum-foam sandwich structures were
completed numerically. Foam and aluminum (Al) were used for the core and
surface layers of the sandwich structure, respectively. In addition, an
adhesive was used as a thin film. Natural frequencies and mode shapes of the
sandwich structure were obtained for different thickness core and surface
materials. For this, three different sandwich structures, different thickness
of the core with same surface layers and the same core thickness with different
surface layers thickness, were modeled as SS1, SS2 and SS3. Analyses were performed by ABAQUS/Standard
finite element software. The increase in the thickness of the Al layer
generally caused a decrease in the frequency, but this decrease is not very
dramatic. The increase in the thickness of the core has caused a serious
increase in the frequency of the sandwich structure.
