摘要：
This paper deals with the vibration analysis of 3D structured beams with double sinusoidal pattern. The corrugation depends on different parameters such as orientation, amplitude and wave length of the double sinusoid shape. First, a numerical modeling was built using the Finite Element method. Then, experimental tests of bending vibration were conducted on planar and corrugated beams. These data validated our model and proved that the resonant frequencies generally increase due to corrugated shape. A parametric study demonstrated that the optimal values of the corrugation shape can be found to increase the resonant frequencies. (C) 2017 Elsevier Ltd. All rights reserved.
