Frédéric Barlat,Maeda Yasushi,Kwansoo Chung,Masahiro Yanagawa,J.C. Brem,Hayashida Yasuhiro,D.J. Lege,Kuniaki Matsui,Shawn J. Murtha,Shigeo Hattori,R. Becker,S. Makosey +11 more
TL;DR: In this article, a generalized phenomenological yield description is proposed to account for the behavior of the solute strengthened aluminum alloy sheets studied in this work and the experimental yield surfaces were found to be in good agreement with the polycrystal predictions for all materials and with the phenomenological predictions for most materials.

TL;DR: In this paper, yield surfaces for binary aluminum-magnesium sheet samples were measured using biaxial compression tests on cubic specimens made from laminated sheet samples, and the yield surfaces were also predicted from a polycrystal model using crystallographic texture data as input and from a phenomenological yield function proposed previously.

TL;DR: In this paper, a combination of a mathematical model for recrystallization of austenite and a computer simulation for strain and temperature analyses were performed in order to predict the grain size distribution in the through-thickness direction.

TL;DR: In this paper, the yield surfaces of binary aluminum-magnesium alloy sheet samples were measured using biaxial compression tests and the effects of friction and elasticity of the die were accounted for with the aid of finite element method (FEM) simulations.
