The purpose of this study is to propose a new numerical modeling of adhesive joint of CFRP laminated composites. The proposed model is constructed with shell and beam elements, that correspond to adherend and adhesive, respectively. In case that the new numerical model is applied to the eigenvibration analysis under the canti-levered condition, the validities are first checked by comparison with experimental results. Using this model, influences of adhesive and adherend properties and adherend thickness upon eigenfrequency are also discussed. Therefore hoop positions of the 1st and 2nd eigenvibration modes of CFRP adhesive joint are an free end of specimen and the adhesive, respectively. In particular, it is confirmed that the 2nd eigenfrequency depends on shear deformability in adhesive layer.
