A method for predicting and analyzing the ultimate load of the double-sided repaired structures of composite laminates subjected to tensile load was proposed. A three dimensional FEA model was established to analyze the damage process. The adhesive layer was modeled with the isotropic constitutive. A square criterion based on three direction shear strains to predict the occurrence of the damage of the adhesive layer, and a degradation function associated with the stress and strain was defined to degenerate the stiffness of the damaged material. The composite laminates was modeled with the orthotropic constitutive, and the occurrence of damage was predicted by 3D Hashin’s initiation criterion and Ye criterion. Damage variables was introduced to characterize the damage extension. The ultimate load obtained from the numerical prediction agreed well with the experimental results. It is verified that the method and model can predict the tensile ultimate strength of the double-sided repaired composite laminate structures effectively.
