Design of Sandwich Structures for High Vibration and Noise Conditions
Sandwich materials that are considered to have lightweight, well-flexural behavior, in addition to relatively high structural damping are considered significant by aerospace sectors due to the usage of such materials in specific aircraft applications including helicopter interior parts where vibrations and noises of high levels take place. The primary purpose of the research is to concentrate on sandwich structures with high damping values and appropriate flexural rigidity.

Experimental and numerical vibration analysis of GLARE beams
In this paper, the dynamic behavior of glass-reinforced aluminum laminate epoxy (GLARE) beams was examined via experimental and numerical methods. Four beams were manufactured with different fiber orientations and tests were conducted by using a non-contact experimental setup with clamped-free boundary conditions. It was found that different fiber orientations have effects on the natural frequencies of the beams.
