Determination of Plastic Anisotropy of Extruded 7075 Aluminum Alloy Thick Plate for Simulation of Post-Extrusion Forming

In this study, the plastic anisotropy distribution of an extruded 7075 aluminum alloy thick plate was evaluated through small-cube compression tests. The with a thickness 15 mm divided into five layers in order to verify difference along direction plate. Small-cube specimens side length 1 were extracted from each layer and subjected tests evaluate directional r-values material. applied Hill’s quadratic yield criterion calculate six coefficients for layer. To consider direction, finite element model applied. Upsetting conducted accuracy analysis using cube 10.6 mm, results upsetting test compared analyzed against other. Consequently, analyses precisely simulated results.
