“…In the middle of the sheet the impact of curvature of the flow line in this shear is negligible. Another shear component, nearly constant within the sheet, is also generated by the different circumferential velocities of the rollers and operates in the ND plane and in the RD direction [33][34][35][36][37]. This approach is also adopted in the present work.…”

“…Several lattice planes commonly used to perform lattice strains measurements in XRD [8,[38][39][40][41][42][43] and ND [44][45][46][47][48] have been investigated. In order to compare the influence of the morphologic texture on stress analysis by XRD and ND methods, we have chosen to present only the results obtained for (hkl) planes in common to these two diffraction techniques (see Table 2).…”

International audienceIn this work, a study on the influence of morphologic texture on the residual stress determination by diffraction in metallic materials with cubic and hexagonal symmetry is proposed. To this end, elastic self-consistent model has been developed to properly take into account the morphologic texture. Extreme crystallites morphologies (sphere, disc and fiber) were studied, and coupled with the crystallographic texture to reflect the combined effect of morphologic and crystallographic texture in elasticity. In the case of morphologic texture, a stronger influence than the crystallographic texture on the estimated residual stresses (several tens of MPa difference) was observed. We propose a methodology through a scale transition model to take into account the influence of these different morphologies in the stress analysis by diffraction methods. The main purpose of this work is to make the best choice for lattice planes (hkl) used for residual or internal stress analysis, in elasticity, depending on the morphologic (and crystallographic) texture of the polycrystal, especially when the usual X-ray Elasticity Constants (XECs) are used instead of the stress factors

“…The existing literature on mechanical modeling of the anisotropy of zinc alloys is, as expected, based on micro-mechanical approaches [10,11]. Micro-mechanical modeling provides a link between the microstructure of a material and its mechanical behavior, allowing us to quantify plastic deformation at the microstructural level.…”

“…This approach is thus well-suited for simulations involving material texture and related anisotropy. A considerable amount of simulation has been performed using "physically based" models rather than simply fitting phenomenological behavior laws in the literature [10][11][12][13][14][15][16][17][18][19][20].…”

A B S T R A C TZinc and its alloys are important industrial materials due to their high corrosion resistance, low cost and good ductility. However, the characterization of these materials remains a difficult task due to their highly anisotropic behavior, the latter being due to the influence of microstructural effects, i.e. loading orientation-dependent activation of different families of slip systems and subsequent texture evolution, rendering the development of a reliable material model considerably difficult. A micro-mechanical approach based on polycrystal plasticity would better describe the physical mechanisms underlying the macroscopic behavior. This improved model should ostensibly improve the comprehension of the mechanical behavior, compared to the macroscopic approach using solely phenomenological anisotropy models along with a prohibitively large number of experiments required to identify the material parameters. In this paper, a multi-scale Visco-Plastic Self-Consistent (VPSC) approach is used. It is based on a micro-scale model calibrated by microstructural and deformation mechanism information based on Electron Back-Scattered Diffraction (EBSD) to describe the macroscopic anisotropic mechanical response during sheet metal deformation. The critical resolved shear stress (CRSS) as well as the micro-scale crystal parameters are obtained by an inverse analysis comparing the simulated and experimental results in terms of obtained tensile curves along three different directions. In order to obtain a global solution for the identification, we then use the Covariance Matrix Adaptation-Evolution Strategy (CMA-ES) genetic algorithm to the inverse problem. We validate our approach by comparing the simulated and experimental textures and activated slip systems. Finally, the identified mechanical parameters are used to investigate the anisotropy of the alloy and predict its formability by determining the corresponding R-values and Hill yield coefficients.
