A simple solution procedure of predicting the strength of adhesively bonded single-lap and lap-shear unbalanced joints with nonlinear adhesive properties was developed by following the global/local analysis procedure developed by Goland and Reissner (1944). Simple formulas for the shear and peel strain energy rates of the joints were obtained in terms of the longitudinal membrane forces and the bending moments in the adherends after neglecting the terms related to the transverse shear forces. Two simple failure criteria were suggested and then validated by comparing to the measured failure envelopes and correlating with the measured strengths of the lap-shear and singlelap joints. It was shown that neglecting the terms related to the transverse shear forces could yield an over estimation of both energy rates for the single-lap joints with relatively stiff adhesive, c~7~

This paper deals with a numerical investigation on double-lap and symmetrical single-lap joints subjected to shear/bending moment and axial force. The analysis has been developed using the theoretical model proposed by the author in [Ascione F. Mechanical behaviour of FRP adhesive joints: a theoreti
It is well known that geometric nonlinear effects have to be taken into account when the ultimate strength of single lap composite joints are studied. In the present paper we investigate for which level of loads or prescribed end displacements nonlinear effects become significant and how they appear
