摘要：
This paper analyses the vibration of FGM Timoshenko beam based on graded mode of exponential function. The material properties are assumed to vary as an exponent form of thickness coordinate variable. The free vibration equations of FGM beam are derived by Hamilton principle, and the equations of natural frequencies for a simply supported FGM beam are presented. The influences of functionally graded index difference and different metal material and span-depth ratio that influence vibration frequencies are finally discussed.
