A macro–micro-multi-level modeling scheme to study the effect of particle distribution on wrap-bendability of AA5754 sheet alloys

A two-level finite element model to simulate wrap bending of flat sheet metal has been developed. Firstly, a sample sized plane strain analysis is performed and the location of most severe deformation is identified. Then a plane strain sub-model incorporating microstructural input, such as second phase particles at this location, is performed. The results show that models with particles distributed primarily in stringers exhibit lower …
