Abstract: Recently, bonded joints have found their growing applications especially in the various fields of construction industry. Due to the mismatch in Poison's ratios and the coefficients of thermal expansion of adjacent adherents, which are mainly responsible for debonding failure, there are high boundary layer interfacial stresses on free edges. Therefore, it is crucial to examine the mechanical behavior of such joints when Integrated as structural elements. The present study proposes two shear and normal stress functions in order to explicitly and accurately predict interfacial stress distributions along the bonding line. A concise MATLAB code was designed to execute the proposed task. In addition, a scaling analysis was performed on a CFRP-bond bonded joint to examine the dependences of the interfacial shear and normal stresses on the geometric and mechanical properties of adherents. The current framework can be conveniently extended to mechanical and thermal stress analyzes of various bonded structures under different types of loads
