単層CFRP薄板の物性値同時同定手法の考案

抄録

This study investigated the material properties identification method of a single layer CFRP plate. This identification method is comparing between the vibration mode measurement results obtained from anisotropic materials with vibration analysis results of a single layer CFRP plate. In particular, genetic algorithm was used to identify multiple material properties at the same time. The usefulness of the identification method was confirmed by using simulation data and experimental data. When the evaluation function is raised to the power, the variation is reduced. Also, it was found that taking an average value results in a reasonable value. In the experimental data, it was possible to identify with a goodness of fit of 95%.
