Abstract :
1-3-2 composite is made of 1-3 composite and ceramic base. The influence of piezoelectric phase volume fraction and composite aspect (thickness/width) on resonance characteristic of square 1-3-2 piezoelectric composite plate has been researched in ANSYS. The resonance frequency of 1-3-2 composite samples was investigated. The result shows that when the volume fraction of ceramic rods is about 0.46 in the 1-3-2 composite model of ANSYS, The result of simulation will be perfectly close to the data of experiment. The contour mode 8 among contour -extensional modes would disturb the thickness mode when the ratio of thickness to width is more than 0.3.
