“…Numerical simulation appears thus as an appealing resort to analyze the vibration response of assembled components [12]. In [13], the authors used a finite element modeling of adhesive bonded plates to investigate the effect of different model parameters on the global system mode shapes. However, numerical simulation is generally time-consuming in industrial settings.…”

In industrial settings, engineering products are often divided into separate components for detailed conception. They often require iterative corrections between different designers/teams to optimize the final product with all components assembled into a system. This article proposes a surrogate modeling approach with functional descriptions of parts in the model and aims to accelerate the design and optimization phase in real projects. The approach is applied to a vibration problem of a two-component plate structure, where the model estimates the dynamic behavior of the assembled system when only the properties of each individual part are available. A database is built using high-fidelity numerical simulations, and neural-network-based regressions provide reliable predictions on unseen data.

“…Adhesive bonding, on the other hand, offers a wider area for stress distribution and reduces the time and costs of fabrication. In addition, this joining technique seems to be convenient for composite assembling where drilling and disrupting are avoided [1][2][3].…”

Double lap bonded glass-epoxy composite assemblies were tested under static and cyclic shear condition loading where the static shear strength and the number of cycles to failure were measured, respectively. Araldite 2031 epoxy was the adhesive used having a glass transition temperature of 65 °C. In order to verify the influence of the thermal ageing on the adhesive behaviour, three different thermal treatments of the assemblies were adopted: one below the glass temperature (unaged) and 2 aged for 1 and 2 weeks, respectively, at 10 °C above the glass temperature. It was found that the latter case has shown the highest shear strength and number of cycles to failure. Scanning electron microscopy analyses of the adhesive-substrate interfaces for the three ageing configurations have shown best adherence for the 2-week aged specimens. Moreover, series of thermal stability analyses of the adhesive picked up from the fractured specimens from the three types of ageing have confirmed the results: thermogravimetric analysis has shown that the degradation temperature was not reached during any of the adopted thermal ageing configurations, while differential scanning calorimetry has spotted on the stability status of the adhesive pointing out the improvement in morphology and even the increment of transition temperature, and finally Fourier transform infrared spectroscopy analysis has confirmed the absence of oxidation of the adhesive under all ageing configurations.
