a b s t r a c tAdhesive joints have a wide range of applications in the civil engineering, automotive and aircraft industries. In the present research, we use the finite element method to systematically study the overall strength and interface failure mechanism of single lap joints, which are subjected to tensile loading, focusing on the effects of various system parameters including fracture energy of the adhesive layer, overlap length and adhesive layer thickness on the load-bearing capability of the joints. The results show that the overlap length and the adhesive fracture energy have combined influences on the load-bearing capability. On the other hand, a preliminary damage analysis of the adhesive layer is carried out, considering the situations when the loads arrive to the peak values. Furthermore, the interface behavior is investigated, including the interface stress analysis and interface slip. The rotation of the joint during loading and its influence factors are studied as well. Obtained results suggest that the interface stress distributions are related to the slip and the rotation angle.Crown

“…pure flexural debonding of a plate end located in a pure bending region (simply 'flexural debonding') and pure shear debonding of a plate end subjected to a 9 high shear force but little or no moment (simply 'shear debonding') [33][34][35][36][37][38][39][40][41][42][43]. For a simply-supported CRL strengthened RC beam, the shear debonding can be considered as the control debonding failure if the bond length of CRL is enough (e.g.…”

“…These facts indicate that at the interface mechanical bond does not deteriorate but chemical bond does. The deterioration of bond due to moisture can be described by bond stress-slip relationship (t -s), which can be obtained from FRP strain-slip relationship (e -s) as shown below (Dai, Ueda, & Sato, 2005);…”

In order to develop rational guidelines for strengthening by external bonding, it is necessary to clarify longterm performance of interfacial bonding property. In this paper, moisture effects on bonding properties at FRP-concrete interface and temperature/moisture effects on bonding properties at PCM-concrete interface are presented. Shear bond strength of FRP-concrete interface is affected by moisture because resin-concrete adhesion strength is affected by moisture. Among tested CFRP external bonding systems, wet-layup CFRP systems all show the strength reduction, while prefabricated CFRP systems all show the strength increase after immersion. The bond stress-slip relationship and interfacial fracture energy also change, which can explain the change in shear bond strength. The reduction in shear bond strength does not show clear dependency on resin strength/stiffness reduction. The observed big variation in shear bond strengths reported in past studies can be explained by difference in interface roughness, since chemical bond is affected by moisture but mechanical bond is not. Tension/shear bond strength of PCM-concrete interface is affected significantly by temperature but less by moisture. The tensile/shear bond strength is less than tensile/shear strength of constituent materials (PCM and concrete). The reduction in tension/shear bond strength depends on the reduction in tensile/shear strengths of PCM and concrete and then estimated by proposed equation which is a function of PCM and concrete strength. The ultimate loads of beams strengthened by PCM overlay can be predicted by the proposed model in which the proposed tensile/shear bond strength is applied. Under high temperature, the failure mode can be changed from flexure/shear failure to debonding failure due to the reduction in shear bond strength.
