خلاصه مقاله:

In this paper the influences of different loading conditions such as axial, shear and bending moment and effect of thickness of adherends and adhesive layer on stress distribution of adhesive joint are investigated. For these investigations, a mathematical modeling for analysis of adhesive joints in composite structures is present. In this model adherends are orthotropic laminates that obeys classical lamination theory, they can be either symmetric or asymmetric. Adhesive layers are made of homogeneous and isotropic materials. In this research, constitutive relations, kinematic and equilibrium equations are derived for each of the inside and outside of overlap zones.
