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, void growth and ductile failure in the non-uniform multiaxial stress fields of notched bars are studied numerically and experimentally, using an elastic-viscoplastic constitutive relation that accounts for strength degradation resulting from the growth of microvoids.

TL;DR: In this article, the orientation changes of a set of grains in a 2 × 2 mm region on an internal surface of a two-part polycrystalline aluminum sample were measured by the Backscattered Kikuchi Diffraction (BKD) technique before and after 40% height reduction in a channel die.

TL;DR: In this paper, a plane-strain tensile failure of a low carbon steel containing stringered manganese sulfide inclusions is analysed, where the relatively soft, noncoherent inclusions are modeled as voids.
