Journal ArticleDOI
Effect of texture and microstructure on strain hardening anisotropy for aluminum deformed in uniaxial tension and simple shear
Augusto B. Lopes,Frédéric Barlat,Frédéric Barlat,José Grácio,J. Ferreira Duarte,Edgar F. Rauch +5 more
TL;DR: In this article, uniaxial and simple shear stress-strain curves were obtained for a 1050-O aluminum alloy sheet sample in different specimen orientations with respect to the material symmetry axes.
Journal ArticleDOI
Hardening behavior and structural evolution upon strain reversal of aluminum alloys
Edgar F. Rauch,José Grácio,Frédéric Barlat,Frédéric Barlat,Augusto B. Lopes,J. Ferreira Duarte +5 more
TL;DR: In this paper, the authors analyzed the mechanical behavior and the dislocation structure change upon strain reversal for AA1050-O and AA6022-T4 aluminum alloys.
Journal ArticleDOI
A more general model for forming limit diagrams prediction
TL;DR: In this paper, the authors developed a more general code for the prediction of forming limit diagrams (FLDs), which is composed of a main part and several subroutines, which allow the implementation of different hardening laws, yield functions or constitutive equations.
Journal ArticleDOI
The performance of Yld96 and BBC2000 yield functions in forming limit prediction
M.C. Butuc,Dorel Banabic,A. Barata da Rocha,José Grácio,J. Ferreira Duarte,P. Jurco,Dan Sorin Comsa +6 more
TL;DR: In this paper, the performance of two non-quadratic yield functions for orthotropic sheet metals under plane stress conditions, namely Yld96 and BBC2000, on forming limit prediction was evaluated.
Journal ArticleDOI
The use of finite element simulation for optimization of metal forming and tool design
TL;DR: In this article, the authors present the modelling of components with complex shape to be manufactured by closed die forging and sheet metal forming and one tries to show how numerical simulation may help in defining the shape and size of initial material or blank and predict the forces needed to define the press to be used in the process, as well as the possible defects.
