“…Whereas many models for thermomechanical processing are restricted to studying either the texture development due to deformation (e.g. [25][26][27]) or the changes in the microstructure due to dynamic recrystallization (e.g. [28,29]), the proposed model is capable of capturing both.…”

A multiscale modeling framework, combining a graph-based vertex model of microstructure evolution with a GPU-parallelized crystal plasticity model, was recently proposed by the authors. Considering hot rolling of copper, the full capabilities of the model are demonstrated in the present work. The polycrystal plasticity model captures the plastic response and the texture evolution during materials processing while the vertex model provides central features of grain structure evolution through dynamic recrystallization, such as nucleation and growth of individual crystals. The multiscale model makes it possible to obtain information regarding grain size and texture development throughout the workpiece, capturing the effects of recrystallization and heterogeneous microstructure evolution. Recognizing that recrystallization is a highly temperature dependent phenomenon, simulations are performed at different process temperatures. The results show that the proposed modeling framework is capable of simultaneously capturing central aspects of material behavior at both the meso- and macrolevel. Detailed investigation of the evolution of texture, grain size distribution and plastic deformation during the different processing conditions are performed, using the proposed model. The results show a strong texture development, but almost no recrystallization, for the lower of the investigated temperatures, while at higher temperatures an increased recrystallization is shown to weaken the development of a typical rolling texture. The simulations also show the influence of the shear deformation close to the rolling surface on both texture development and recrystallization.

“…Enhancing the plastic strain ratio in Al alloys requires a detailed understanding of texture evolution during TMP. In general, the crystallographic texture of metals, evolved during TMP, is mainly affected by the degree of deformation, strain mode, recrystallization temperature etc [1][2][3][4][5]. The influence of technological parameters on both microstructure and texture is not entirely understood and can be revealed by means of numerical approaches, dealing with (i) strain distribution in deformed material, (ii) strain partitioning in polycrystalline aggregate and (iii) stress relaxation in a given crystal subjected to internal or external influence.…”

A brief summary on modeling the deformation textures by means of well-established crystal plasticity (CP) theories is presented in the current contribution. The simulations are carried out by combining Taylor-type homogenization approaches, dealing with the partitioning of macroscopic strain in a polycrystalline aggregate, and models based on principles of continuum mechanics (CM). The performance of the full constraints Taylor, advanced Lamel, viscoplastic self-consistent and Cluster V CP models, is discussed. The rolling first was approximated by plane strain compression, though it was shown that an improvement in texture simulation is reached by considering heterogeneities of deformation flow across the thickness of a rolled sheet. Results of simulations by means of geometric, flow-line and finite element models indicate that the deformation history can be captured with different degree of accuracy depending on the complexity of a given CM-based approximation. It was shown that the analytical flow-line approach accoupled with particular CP model is capable of providing texture prediction comparable to one simulated with the strain path obtained by means of finite element modeling.

“…Various micromechanical models were developed in order to describe the evolution of highly heterogeneous materials as metallic polycrystals or composites (Bornert et al, 2001;Boudifa et al, 2009;Cailletaud and Pilvin, 1994;Chen et al, 2017;Gawad et al, 2013;Goidescu et al, 2015;Hfaiedh et al, 2009;Jiang et al, 2016;Ju and Wu, 2016;Nasser, 2004;Raabe, 1998;Ren et al, 2017;Saanouni, 2012;Soho et al, 2017;Suquet, 1997;Van Houtte et al, 2012;Wu and Ju, 2017;Zhu et al, 2015Zhu et al, , 2016. The finite element method (FEM) combined with crystal plasticity (CP) modeling (CPFEM) was used by some authors to study the deformation texture development in polycrystalline aggregates, whereas some others used CPFEM to describe heterogeneous local (intra and intergranular) strain and rotation fields during monotonic loading paths as well as strain localization after several loading path sequences.…”

In this paper, a multiscale model of ductile damage and its effects on the inelastic behavior of face centered cubic polycrystalline metallic materials, such as the evolution of their crystallographic textures, are investigated. The constitutive equations are written in the framework of rate-dependent polycrystalline plasticity at the microscopic scale. Plasticity and damage are coupled through a ductile damage variable introduced at the scale of the crystallographic slip systems of each grain. When homogenized to the macro-scale, this becomes an approximate phenomenological measure of the macroscopic ductile damage which can describe the material degradation by initiation, growth, and coalescence of micro-defects. In this paper, thermally activated intergranular (or creep) damage is not taken into account. Both theoretical and numerical aspects of the model are presented. The model is implemented into a general-purpose finite element code in order to analyze the effects of texture evolution and ductile damage initiation in the grains with favorably oriented slip systems. The capability of the proposed model to predict the plastic strain localization and the induced textural evolution, as well as the effects of the ductile damage and its evolution up to the final macroscopic failure are studied for a classical tensile loading path, applied to a representative volume element and to a 3D tensile specimen on which a parametric study has been carried out.
