A model based on the Element Free Galerkin (EFG) method in the framework of linear elastic assumptions was developed to determine the distribution of interfacial stress in a concrete beam reinforced with FRP plates. In this model, the behavior of the adhesive layer between the surfaces is considered like a linear spring using its elastic properties, and MLS approximation functions are used to approximate the total displacement fields. In addition, the results were calculated and presented under the condition of complete adhesion between the surfaces. The results of the model were compared with the FEM model in Abaqus software for concrete beam and FRP panel. The results show that the EFG method has a good agreement with the outputs of the Abaqus model. To conclude this work, a parametric study was performed. It shows how the thickness of the adhesive layer and the FRP plate affect the shear and normal stress values of the adhesive.
