“…Thus, while modelling constructed systems, the natural dynamics interface relationships must be taken into account [4]. An improved understanding of nonlinear behaviour in bolted joints can be achieved by enhancing the models with cubic stiffness nonlinearity, resulting in a more accurate depiction of the actual behaviour of bolted joints [5,6]. An complete four-parameter model that takes into account non-Gaussian surface flaws ,accurately describes the nonlinear stiffness behaviour of bolted joints [7].…”

Engineering applications require accurate modeling and parameter identification to anticipate bolted joint behavior under different loading circumstances. Bolted joints are extensively used in civil and mechanical structures. In this research study, cubic stiffness non-linearity is examined and a comprehensive model, which can exhibit the non-linearity of joint behavior, is developed. This is achieved by modeling the bolted joint which is connected at one end of a cantilever beam. Mathematical model is established using concept of sub structure synthesis theory by considering non-linear translational stiffness and non-linear rotational stiffness as a boundary condition. Non-dimensional natural frequencies are estimated by assuming stiffness parameters and joint parameter estimation for translational spring having nonlinear stiffness is calculated using second order curve fitting technique. Furthermore, estimated and exact value of cubic stiffness coefficient are compared. The experimental results shows that the percentage error of estimation for all the modes are less than 8 %. The experimentally determined natural frequencies are further contrasted with an analytical results to validate a precision of generated model. Present work contributes in improving the bolted joint analysis by providing a solid non-linear modeling and parameter identification methodology. This methodology enhances design practices and ensures the durability of engineering structures and mechanical systems by improving bolted joint comprehension.

Due to its many applications' benefits, adhesively bonded joints are widely utilized in nearly every industry, including the space, marine, automotive, and aeronautics. Since unpredicted loadings may cause resonance in the structures, an accurate prediction of the bonded joints' dynamic characteristics is crucial. Therefore, in this study modal analysis on the two-, three-, four- and double-step adhesively bonded lap joints of Aluminum (Al), Copper (Cu) and Mild steel (Ms) materials with Epoxy Araldite adhesive was performed. Ansys commercial program was utilized in order to analyze it numerically. The results showed that modeling the bonding region of single lap joints as two-, three-, and four-step adhesively bonded lap joints has no significant effect on the natural frequencies. This modeling has a minor incremental effect on the natural frequencies. However, Double-step lap joints were found to cause a considerable reduction in natural frequencies compared to not only single lap but also two-, three-, and four-step adhesively bonded lap joints. Double-step bonding caused a decrease of 8,82%, 8.57% and 8.73% for Al-Al, Cu-Cu, Ms-Ms. In general, in all models, the best increase or decrease in terms of natural frequencies was found to for Cu-Cu adhesively lap joints.
