This study discusses identification of material constants of Single-Layer CFRP thin plate using vibration analysis with general purpose FEM code and differential evolution method. This identification method is a method to select material parameters to match the vibration characteristics of the experiment and the vibration characteristics of the analysis. In the method, a general-purpose FEM code calculates vibration modes and natural frequencies of thin CFRP plate using material parameters which are selected by differential evolution method (DE). Some simulation data are used to probe the validity of the identification method. As a result of validation, this method is found to be no different from the conventional method and was found to be valid. Using the simulated data, this method can identify three elastic coefficients of CFRP plate without error.
