“…Moreover, Huang and et al [11] investigated the influence of temperature, impact energy and stiffness combination on residual tensile properties. It was noted that both temperature and impact energy now have a strong correlation with the static properties, and decreasing the relative stiffness ratio can decrease the residual tensile strength of SLJs.…”

In research, composite parts adhesively joined with single-lap joint (SLJ) and intermediated material under tensile load were examined by finite element analysis (FEA). While T700 Carbon/epoxy was used for composite parts and intermediate material, DP 410 type was preferred for adhesive. The numerical studies were carried out by ANSYS 14.5 based on finite elements method. The von-Mises failure criteria and the Tsai-wu failure criteria were respectively considered for adhesive and composites. The analyses were firstly actualized to determine the failure loads for each parameter situation. The stresses at obtained failure load for each parameter state were investigated. The critical equivalent stresses on adhesive layers were examined and the critical stress lines for length and width was determined. The distributions of normal and shear stresses in all directions were obtained by considering critical stress line on adhesive layers. Similarly, the von-Mises stress distributions were obtained. Considering critical stress lines, the stress distributions on width and length of overlap dimensional were compared. The effects of overlap dimensional, orientation angle and intermediated material on effect of joint zone were investigated.

Compared with traditional technology, bonding technology is more suitable for civil structure reinforcement because of its cost‐efficiency and superior mechanical properties. However, research on the long‐term performance of single‐lap joints (SLJs) requires better organization and comprehension. This article aims to investigate the long‐term performance and optimization design of SLJs. The main factors influencing the long‐term performance of SLJs from both material and component levels are discussed. The moisture diffusion mechanisms of bulk adhesives and the degradation mechanisms of SLJs are explored. Moreover, the optimization design of SLJs focuses on evaluating the overlap length, adhesive layer thicknesses, and changes in adhesives along the overlap length based on available literature. It is found that the applicability of diffusion models should be validated, and the selection of the models should consider working environments and types of adhesives. Exploring failure mechanisms and design criteria for the mixed SLJs in hygrothermal environments with/without sustained or alternating load is significant for the optimization design. This article indicates the limitations on the shear strength and long‐term performance of SLJs in available studies and provides insights into the challenges and prospects of their optimization design.
