Natural Characteristics Analysis and Validation of Fiber Metal Laminates Thin Plates Under Cantilever Boundary

The natural characteristics of fiber metal laminates(FMLs)thin plates under cantilever boundary were calculated and validated by combining theory with experiment. According to the structural characteristics of FMLs thin plates， theoretical modeling was carried out based on the mechanics of composite material and classical laminated plate theory. Then， the natural characteristics were solved by using the orthogonal polynomial method. Meanwhile， the calculation processes were proposed. A natural characteristic experiment system of FMLs thin plates was established and the natural characteristics of a TA2/TC500 FMLs thin plate were acquired. It is found that comparing the calculation results of the frequencies with the test ones， the errors are within the range of 1.2% and 4.7%， and the trends of modal shapes are consistent as well， thus the effectiveness of the above method is verified.
