Title: | Numerical Study on the Forming Behaviour of Multilayer Sheets | Authors: | Marques, Armando E. Prates, Pedro A. Pereira, André F. G. Sakharova, Nataliya A. Oliveira, Marta C. Fernandes, José V. |
Keywords: | composite materials; multi-layer sheets; equivalent material; forming behaviour; Numerical simulations; deep-drawing | Issue Date: | 2020 | Publisher: | MDPI | Serial title, monograph or event: | Metals | Volume: | 10 | Issue: | 6 | Abstract: | Nowadays, composite materials are playing an increasingly important role in material forming processes because they can combine remarkable physical and mechanical properties with relatively low weight. The main objective of this work is to study the forming behaviour of multi-layer sheets by finite element analysis. The possibility of replacing the composite by a single equivalent material, with a plastic behaviour similar to that of the composite, was also numerically analysed. This study focuses on two three-layer sheets, each composed of two metallic outer layers and a core of polymeric material; on one of the sheets, the outer layers are steel and, on the other, aluminium. Numerical simulations of the bulge test and of the deep drawing of a U-channel profile and a square cup were used to evaluate the behaviour of the multi-layer sheets and their equivalent materials. The influences of the di erence of the mechanical properties of the constituent materials and some geometrical parameters of the deep-drawing process on the plastic behaviour, namely the curves of force vs. displacement of the punch and the strain and stress distributions, were evaluated. The possibility of using the bulge test to characterize the behaviour of the composite was also analysed. | URI: | https://hdl.handle.net/10316/106443 | ISSN: | 2075-4701 | DOI: | 10.3390/met10060716 | Rights: | openAccess |
