  Abstract

Co-cured metal/GFRP joints with groove structures can maintain the integrity of GFRP and the continuity of glass fibres. To improve the performance of the groove structure, it is necessary to design groove parameters (groove depth, width, etc.). Due to the repetitive structure of the groove morphology, the representative volume element (RVE) was used to build the model. Then, shearing and pulling-out simulations of the groove structures were carried out, and the simulated results were compared with the experimental results. In addition, the influence of groove depth and width on the bonding performance of the structures was studied, and the optimal result was obtained (width: 1.00 mm, depth: 0.75 mm). Finally, the ±45 ° groove structure (width: 1.414 mm, depth: 1.00 mm) was equivalent to a 0-thickness cohesive element layer through the stiffness equivalent method, and the results were compared with the previous test (DCB and shear test) results, and similar results were obtained. The equivalent analysis not only verifies the applicability of the stiffness equivalent method but also verifies the practicability of the groove structure obtained by the RVE model.
