“…Nowadays, laminated steels are used in different industries, such as aerospace, nuclear, and food production. Furthermore, not only do two-layer metallic sheets have industrial applications, including automobile, aerospace, electrical, and chemical industries [19][20][21][22][23][24][25], but also domestic applications due to their advantages, such as improving the formability of low-formable components, increasing the wear resistances, and decreasing the spring-back [26,27]. Different techniques have been implemented for welding different metals using explosive welding [28].…”

This study investigates the mechanical properties and microstructural characteristics of explosion-welded Al/Cu two-layer strips during the ECAR process using finite element simulations and experiments. Furthermore, the explosion-welded Al/Cu two-layer strip was examined with various configurations to determine the effects of die angle and friction coefficient on the distributions of effective strain and stress. In addition, the experimental and computational approaches were utilized to explore the ECAR process in two routes, RA and RC, for three directions. Finite element simulations were run and validated using experimental data. The findings show that the ECAR method is effective to enhance the mechanical characteristics of the strips. Moreover, the obtained results represent that the ECAR process reduced the size of the grains. Furthermore, it was shown that by increasing the number of routes in the ECAR process, the stress values were increased. However, the ductility of the two-layer strip was decreased. According to the current study, the route and the number of routes used in the ECAR process have a considerable effect on the strength of the two-layer strip.

“…Investigations about the FLC-determination of FML based on metal sheets and organosheets regarding the influence of temperature changes are rarely found in the literature survey. Some studies reported to use chopped fibres for a reinforced core in the thermoplastic-based FML under RT, in which the formability of FML is proven to be good due to the poor mechanical properties of GF-Polyurethane (GF-PU) as a core layer in this Al/GF-PU hybrid system [36]. The GF-PU used in the FML has a high elongation at failure of ~15% and absolute low stiffness, i.e., elastic modulus of 1.7 GPa [36].…”

A similar study to determine the FLC of FML based on Al5005/self-reinforced PP/Al5005 at RT is performed in [37], in which the strain evolution of thermoplastic-based FML was found to be larger than that of monolithic Al sheets and therewith a higher FLC level and better formability of thermoplastic-based FML.…”

This paper focuses on investigating the forming behaviour of sandwich materials composed of steel sheets and glass fibre-reinforced polyamide 6 (GF-PA6), i.e., thermoplastic-based fibre metal laminates (FML). Stretching and forming limit curve (FLC) determination of FML with different cover/core layer thickness ratios at various forming temperatures, i.e., at room temperature (RT), 200 and 235 °C, are the main approaches for characterizing their formability. In addition, the formability of mono-materials and non-reinforced sandwich materials is investigated as a reference. For a successful test and reliable results, several technical issues are considered, such as the suitable lubrication configuration and digital image correlation at elevated forming temperatures. The results revealed that the formability of non-reinforced sandwich materials with different core layer thicknesses exhibited compared formability to their monolithic steel sheet and no remarkable improvement in their formability with increasing the temperature up to 200 °C. Conversely, the formability of FML shows significant improvement (approx. 300%) with increasing temperature with a forming depth of about 33 mm at 235 °C compared to only 12 mm at RT.
