Tailored welded blanks allow the combination of different materials and different sheet thicknesses in a single blank, thus letting designers and engineers to fit, in initial blank, local needs of strength or other demands in the stamped component. T

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. For uniaxial tension, a strong anisotropy of strain hardening was o

The objective of the work presented here is to assess the performance of two non-quadratic yield functions for orthotropic sheet metals under plane stress conditions, namely Yld96 and BBC2000, on forming limit prediction. The similitude and the diffe

The present paper is devoted to the development of a more general code for the prediction of forming limit diagrams (FLDs). For this purpose, the Marciniak–Kuczynski (M–K) theory is treated with a new approach. The code is composed of a main part

When producing a new component there is usually a trial and error stage to tune the process in order to obtain a part without defects, using the right quantity of raw material. At this stage, the previous experience of designers and manufacturers sho

In order to clarify the relative influences of texture and grain size on the plastic response of a 1050 Al alloy, some tensile tests have been performed after various annealing treatments (designed to obtain different grain sizes) and initial and fin

The last decade has witnessed many advances and a lot of improvement in FE codes for simulation of sheet metal forming processes. Such advances could be followed mainly by benchmarks proposed in Numisheet conferences. It was possible to notice that t
