Analysis of ESAFORM 2021 cup drawing benchmark of an Al alloy, critical factors...
Habraken, Anne Marie; Aksen, Toros Arda; Alves, José L.; Amaral, Rui L.; Betaieb, Ehssen; Chandola, Nitin; Corallo, Luca; Cruz, Daniel J.This article details the ESAFORM Benchmark 2021. The deep drawing cup of a 1 mm thick, AA 6016-T4 sheet with a strong cube texture was simulated by 11 teams relying on phenomenological or crystal plasticity approaches, using commercial or self-developed Finite Element (FE) codes, with solid, continuum or classical shell elements and different contact models. The material characterization (tensile tests, biaxial...

Numerical and experimental analysis of the anisotropy evolution in aluminium al...
Vincze, Gabriela; Lopes, Augusto; Butuc, Marilena C.; Yánez, Jesús; Lopes, Diogo; Holz, Laura; Graça, Ana; Pereira, António B.One of the most important characteristics of the sheet metal is its anisotropy. Asymmetric rolling (ASR) shows to be an adequate process to change the material anisotropy by increasing the normal anisotropy and decreasing the planar anisotropy. In this work, it is analysed the relationship between anisotropy and texture evolution using experimental and numerical approaches. Experimentally, the texture is modifi...
Mechanical Behavior of Al-SiC Nanocomposites Produced by Ball Milling and Spark...
Gracio, Jose J.; Picu, Catalin R.; Vincze, Gabriela; Mathew, Nithin; Schubert, Thomas; Lopes, Augusto; Buchheim, ClaudiaAl-SiC nanocomposites were prepared by high energy ball milling of mixtures of pure Al and 50-nm-diameter SiC nanoparticles, followed by spark plasma sintering. The final composites had grains of approximately 100 nm dimensions, with SiC particles located mostly at grain boundaries. The samples were tested in uniaxial compression by nano- and microindentation in order to establish the effect of the SiC volume f...
