## 1 Introduction
Improvement in the Goland and Reissner model proposed by [PERSON] was examined. The improvement in the Goland and Reissner model proposed by [PERSON] concluded that the single lap joints studied would be more appropriate to explain their mechanical behavior. As a result, they determined that the proposed alternative methodology would be a good way to predict the moment of bending [44]. In their study, [PERSON] et al. (2020) conducted an experimental examination of the tensile property of single-lap joints in carbon-fiber-reinforced bismaleimide (BMI) resin composite laminates. The effect on the tensile feature of single lap joints of the stacking order and width/diameter ratio of composite laminates with three joint configurations, which are bolted, bonded with adhesive and hybrid bolted/bonded single lap joints, was discussed. They concluded that the stacking order and W/D ratio are important in the design of the joints, and the bolts in hybrid joints can increase the tensile property after adhesive failure [45]. In their study, [PERSON] et al. (2018) conducted a comprehensive study of the composite single-lap joints with adhesive-resistant strength. They created 3D open models of single-lap joints with different overlap lengths which were subjected to uniaxial tensile load. They compared the efficiency and accuracy of the models, load-displacement curves, and damage morphology with numerical and experimental results. They concluded that the load displacement curves were consistent with the experimental results and that the fault morphology could be predicted according to the model types [46]. In their study, [PERSON] et al. (2021) examined the capabilities of the single lap multi-bolted composite joints and composite bolted joint elements (CBJEs). In particular, it was shown that a simplified FE model, which includes shell elements to simulate plates and CBJEs for the bolted zone, can reliably determine the bolt load distribution and secondary bending of the joint. They compared experimental data of single lap three-bolted composite joints with FE theoretical data. They concluded that the obtained data could be used profitably for the design of the joint [47]. In their study, [PERSON] et al. (2019) investigated both the mechanical behavior and damage mechanism of riveted, joined and hybrid carbon fiber-reinforced plastic (CFRP)-aluminum joints with various overlap lengths. They analyzed the load-displacement curves, peak load, energy absorption, and joint stiffness. They used high-resolution micrographs of the broken surface to understand various failure modes in the CFRP-aluminum composite by taking typical failure development photos with a high-speed camera for progressive failure analysis. According to the experimental results, they showed that hybrid joints offer superior performance in terms of peak load and energy absorption, increasing up to ~380%, 434% and ~19%, 56%, respectively, only when compared to riveted and joined joints [48]. In the light of the literature studies, in this study bonded, bolted and bolted-bonded single lap joint elements were mechanically analyzed under the static tensile and bending loads. Acryton 1E1, a high-performance, acrylic-based metal adhesive, was preferred as an adhesive. In recent years, AZ91 magnesium alloy and carbon fiber plate materials used in the aerospace and automotive industries due to their mechanical properties such as high specific strength and light weight have been deployed as bonding surfaces [49]. This study is unique because the bonded, bolted and bolted bonded single lap joint made with Acryton 1E1 adhesive, which is especially an AZ91 plate material and an Acrylic adhesive type used in the study, is not found in any other study.
