   Abs DOI Bib

   highly deformable Mg-Zn-Nd-Y-Zr alloy was investigated in terms of anisotropic and temperature-dependent mechanical behavior, with an emphasis on the microstructural changes. Uniaxial tension tests were conducted along the rolling (RD) and transverse (TD) directions at room temperature (298 K) and at 498 K, during which a series of ex-situ EBSD scans were obtained. In addition to quantitative texture analysis based on the EBSD scans, the relative contributions of various slip systems were estimated via slip trace analysis. Moreover, the effect of static recovery was investigated by additional two-step tension tests with intermediate annealing at 498 K. The microstructure development due to recovery was analyzed via ex-situ EBSD scans by analyzing the grain average misorientation, kernel average misorientation, and in-grain misorientation axis evolution. Experimental results were interpreted using crystal plasticity simulations based on the incremental elasto-visco-plastic self-consistent polycrystal model (\DeltaEVPSC). Remarkably, a single set of parameters sufficed to describe the complex anisotropic and temperature-dependent behavior of the Mg-Zn-Nd-Y-Zr alloy by utilizing a dislocation density-based hardening model (DDH). The recovery, mainly of non-basal dislocations, significantly affected the flow stress responses, which allowed not only to describe the hardening behavior but also the anisotropy, characterized by the R-value and texture.

   Abs DOI Bib

   A commercially-pure titanium sample was investigated using an elasto-visco-plastic self-consistent polycrystal model. Temperature-dependent plastic deformation behavior was described by a dislocation density-based hardening model. The model reasonably reproduced various experimental behaviors, including stress vs. strain curves, diffraction lattice strains, twin volume fraction, and crystallographic texture. The temperature-dependent behavior was interpreted based on the dislocation evolution rules comprised of dislocation generation and recombination in accordance with the Kocks-Mecking rule. The modeling results successfully provided an in-depth interpretation of mechanical behavior of α-titanium under a wide range of temperatures.

   Thermal ratcheting of uranium simulated with a thermo-elasto-visco-plastic self-consistent polycrystal model

   Youngung Jeong and Carlos N Tomé

   Journal of Nuclear Materials, 2024

   Abs Bib

   Uranium polycrystal aggregates accumulate large plastic deformation during thermal cycling in a process known as thermal ratcheting. This process is induced by highly anisotropic single crystal properties, texture, and a complex coupling between thermal, elastic, and plastic mechanisms of deformation. In this study, a thermo-elasto-visco-plastic polycrystal model is developed and applied to the prediction of thermal ratcheting in uranium. The model is based on the evolution of dislocation density on individual slip systems and accounts for static recovery effects. The model captures the plastic relaxation of intergranular stresses induced by thermal cycling and leads to quantitative understanding of the coupling between thermal, elastic and plastic mechanisms, and the important role played by static dislocation recovery in uranium. Results are compared with thermal ratcheting measurements.

   Direct application of elasto-visco-plastic self-consistent crystal plasticity model to U-draw bending and springback of dual-phase high strength steel

   Abs Bib

   The incremental elasto-visco-plastic self-consistent polycrystal model (\DeltaEVPSC) was utilized to describe the constitutive behavior of dual-phase 980 (DP980) steel. A simple baseline modeling approach was chosen: the hardening behavior of each constituent phase in the DP980 steel was described by a simple Voce hardening law without explicitly considering the back stress; and it was assumed that using the same single crystal elastic modulus for ferrite and martensite is sufficiently representative. The adequacy of this baseline modeling approach was evaluated by comparing various mechanical experimental data with model predictions in terms of the stress vs. strain curves obtained from uniaxial tension, tension-compression, and loading-unloading-loading (LUL) tests. Additionally, the evolution of experimental lattice strain data reported in literature was used to validate the phase-specific Voce hardening parameters. Despite its minimalistic modeling description, the baseline \DeltaEVPSC model successfully captured key features: 1) the Bauschinger effect, 2) the decrease in chord modulus, and 3) the non-linearity in the stress vs. strain curves resulting from the LUL test. All three mentioned characteristics are crucial for accurate prediction of springback in sheet metals. The \DeltaEVPSC model, interfaced with a finite element solver (Abaqus/standard) as the user material subroutine, was employed to simulate the Numisheet93 benchmark problem. The strip of DP980 was first U-drawn followed by springback. The model-predicted springback profile aligned well with the experimental results only when stress relaxation was properly considered, resulting in improved predictive accuracy compared to predictions based on a distortional plasticity model.

6. A critical discussion of elasto-visco-plastic self-consistent (EVPSC) models

   Abs DOI Bib

   Two recently proposed elasto-visco-plastic self-consistent (EVPSC) models, based on solving for stress or stress increment, are discussed, and their results are compared with the ones of the visco-plastic self-consistent (VPSC) approach. The advantages and shortcomings of the models are demonstrated, with emphasis on how the grain responses are affected by the time increment and inclusion-medium interaction strength used. Experimental data obtained for an FCC stainless steel is used as the benchmark system for performing the simulations and assessing the reliability of the results. Predictions of stress-strain response of the aggregate, standard deviations in intergranular stress and strain rate, along with the evolution of internal lattice strain are presented and compared, with special focus on their dependence on the incremental approach chosen. We find that the chosen time increment may significantly affect predicted grain responses. To avoid such effect a method based on using two separate time increments is proposed, one for approximating the stress rate and another for actual integration of stress, strain, and state variables. The proposed method successfully eliminates the dependence of results on the time increment used, thus allowing more reliable computations while preserving the computational efficiency of the elasto-visco-plastic model.

   Abs DOI Bib

   An incremental elasto-visco-plastic self-consistent polycrystal model was directly interfaced with a finite element (FE) code and applied to simulations of a mild steel sample subjected to 3-point-bending (3 PB). Emphasis is put in applying this strategy, for the first time, to predict springback responses after various amounts of prestrains. The crystallographic orientation distribution obtained from an EBSD scan was used to assign the initial polycrystalline aggregate for each FE integration point. The RGVB dislocation-density-based hardening model was adopted as the constitutive law, and the parameters were characterized by fitting uniaxial tension and tension-compression flow stress curves. The numerical reliability of the FE simulation results was evaluated via a systematic numerical study in terms of the mesh size, the numbers of grains sampled per each FE integration point and the cross-section points. The model successfully predicts the effect of prestrain on the springback, thus implying that the current modeling approach can be directly applied to industrial forming and springback predictions.

   Finite element analysis using an incremental elasto-visco-plastic self-consistent polycrystal model: FE simulations on Zr and low-carbon steel subjected to bending, stress-relaxation, and unloading.

   The EVPSC model is a general elasto-visco-plastic self-consistent constitutive formalism based on a Homogeneous Effective Medium (HEM) approach that accounts explicitly for microstructural features such as slip, twinning, and crystallographic texture. \DeltaEVPSC is improved with respect to the original model reported in (Jeong and Tomé, 2020) by introducing an intermediate linearization scheme, which leads to better predictive accuracy of intergranular stress and strain distributions in the polycrystal. The \DeltaEVPSC model is interfaced with a commercial finite element solver Abaqus/standard as a user-defined material subroutine (EVPSC-FE). EVPSC-FE shows superior numerical stability and, when using parallel computation and 40 CPU core units, it reduces the computation time by a factor 20 compared to using a single CPU core unit for a structure consisting of 512 solid elements. The \DeltaEVPSC-FE model is applied to FE analyses of Zr and low-carbon steel bars subjected to a sequence of bending, stress-relaxation, and unloading. It is shown that the hereditary effect is responsible for the spring-forward motion during the early stage of unloading, while the elastic recovery mainly drives the subsequent spring-back.

2. An efficient elasto-visco-plastic self-consistent formulation: Application to steel subjected to loading path changes

   International Journal of Plasticity, 2020

   Abs DOI Bib

   A novel elasto-visco-plastic self-consistent (EVPSC) formulation based on the scheme of the homogeneous effective medium is presented. The constitutive behavior of a polycrystal is described as that of an elasto-visco-plastic effective medium interacting with grains treated as elasto-visco-plastic ellipsoidal inclusions. The formulation is based on the definition of a unique elasto-visco-plastic compliance, so avoiding the inconsistency arising from assuming superimposed elastic and visco-plastic interaction laws, as made in similar elasto-visco-plastic models. In addition, the elasto-visco-plastic constitutive equation of crystal and aggregate is formulated in terms of stress increments, which leads naturally to a semi implicit solution scheme. The superior numerical stability and computational efficiency of the new incremental EVPSC model (denoted as \DeltaEVPSC) are demonstrated by applying the model to a 316L austenitic stainless steel and comparing against other elasto-plastic models. The modeling capability for predicting texture, stress-strain response, and Bauschinger effect are demonstrated using a dislocation-density based hardening law applied to low carbon (LC) steel subjected to deformation histories that involve strain-path changes.
