“…Considering that deformation by a combination of slip and twinning, the difference between the uniaxial yield stress in tension and the uniaxial yield stress in compression of the fcc polycrystal would be smaller but of the same sign (see also, Hosford and Allen, 1973). Also, if at single crystal level the deformation by crystallographic does not obey the classical Schmid law, the untextured polycrystal may display a slight tension-compression asymmetry (see Groger et al (2008), Lebensohn et al (2009), Cazacu andBarlat (2008)). Seeger and Holland (2000) have also shown that the flow stress of high-purity molybdenum bcc single crystal exhibits well-defined tension-compression asymmetry.…”

The research interest in titanium alloys lies in the fact that their exceptional mechanical properties make them ideal for specific industrial applications, such as biomedical, aerospace, and military industries. [1][2][3] Despite its high cost, Ti-6Al-4V alloy is currently the most widely used titanium alloy, [4] combining good biocompatibility and corrosion resistance, [5][6][7][8][9][10] high strength, low weight, and ductility. [11][12][13][14][15][16] Several manufacturing processes among the aforementioned applications contemplate the implementation of material characterization procedures, either on pristine samples of the material or on previously manufactured parts. The most commonly applied experimental procedures to identify the macroscopic orthotropic elastoplastic properties of a material include monotonic tensile, [17,18] compression, [19,20] and shear [21,22] tests of material samples obtained from its orthogonal directions. The main limitations of these tests are the size of the specimens and their subsequent destruction,

This paper presents synthetically the most recent models for description of the anisotropic plastic behavior. The first section gives an overview of the classical models. Further, the discussion is focused on the anisotropic formulations developed on the basis of the theories of linear transformations and tensor representations, respectively. Those models are applied to different types of materials: body centered, faced centered and hexagonalclose packed metals. A brief review of the experimental methods used for characterizing and modeling the anisotropic plastic behavior of metallic sheets and tubes under biaxial loading is presented together with the models and methods developed for predicting and establishing the limit strains. The capabilities of some commercial programs specially designed for the computation of forming limit curves (FLC) are also analyzed.
