A major challenge in forming polycrystalline aluminum alloy sheets is their strong plastic anisotropy, namely the flow stresses and plastic strains depend on the loading direction. This plastic anisotropy is due to the anisotropy of the constituent c

There is a large body of literature on both the techniques for bulge testing and experimental results for various metallic materials (see the book of Banabic [1]). Generally, the experimental data for isotropic materials are interpreted using the von

Based on a systematic experimental investigation of the mechanical properties of alumina powder a new general 3-D constitutive model for compaction of powders has been developed. A significant feature of the model is that it describes the time effect

This paper reviews the most recent models for description of the anisotropic plastic behavior and formability of sheet metals. After a brief review of classic isotropic yield functions, recent advanced anisotropic criteria for polycrystalline materia

This extended comment is in response to the letter of Barlat (Int J Mater Form 2020) concerning our recent article (Chandola et al. (Int J Mater Form 12(6):943–954 2019)). The main issue raised is an apparent “mismatch” between some of the F.E.

New expressions in terms of stress components of the Karafillis and Boyce (1993) yield criterion are derived. First, it is demonstrated that the isotropic version of this criterion is a homogeneous polynomial in J 2 and J 3 2 , where J2 and J3 are th

Very recently, it was shown that the orthotropic yield criteria of Barlat et al. [1] and Karafillis and Boyce [2] are in fact simple polynomials (see [3], [5]). Using these new mathematical expressions, the anisotropy coefficients involved in these c

A systematic experimental investigation of the plastic anisotropy at high strain-rates of Ti6Al4V was carried out using a Split Hopkinson bar system. Dynamic tensile tests were conducted on flat specimens cut at seven ori-entations with respect to th
