An evolving plane stress yield criterion based on crystal plasticity virtual experiments

Abstract: This paper presents a new hierarchical multi-scale framework that allows taking into account evolution of the plastic anisotropy during sheet forming processes. The evolution of crystallographic texture, which is identified as the main source of the plastic anisotropy, is predicted by the ALAMEL crystal plasticity model. An extension to the phenomenological anisotropic planestress yield criterion BBC2008 is proposed, which provides adaptive updates of the local anisotropy in the integration points of the macro… Show more

“…As pipes pose difficulty for the measurement of plastic properties (r-values) in tensile testing along directions other than the axial direction, the r-values in the Hill-average yield criterion are calibrated based on an advanced identification algorithm: the crystal plasticity virtual experiment framework (VEF) [13,15]. The VEF is a software suite that manages high-level stress-based virtual testing capabilities (e.g., uni-and multi-axial tensile/compressive testing, yield locus and r-value calculation) for multi-scale plasticity models that have been developed for strain-rate-based input of plasticity, such as ALAMEL.…”

“…Therefore, Van Houtte et al [10] have established the facet method using homogeneous polynomials to describe the plastic potential in either stress or strain rate space, which comprises much more coefficients than the conventional phenomenological constitutive law. These coefficients have been readily derived from a series of virtual experiments performed on the basis of, e.g., the Taylor or the ALAMEL (Advanced Lamel model) models [11][12][13][14][15][16].…”

“…An extension of the BBC 2008 yield criterion has been proposed [51], which provides adaptive updates of the local anisotropy in the integration points of the macroscopic FE model. The BBC 2008 model is systematically recalibrated to the data provided by the crystal plasticity virtual experiment framework (VEF), using the advanced LAMEL model crystal plasticity model developed at the Catholic University Leuven [52].…”
