Special Issue Information

Dear Colleagues,

The last few decades have seen a considerable progress in the development of high performance metals and alloys that have microstructures and plastic behaviors with a high level of complexity. Ultrafine-grain materials, high-entropy alloys, and metallic glasses have been the focus of research and are gaining a place in the industry. Concurrently, the collective, heterogeneous, and self-organized nature of plastic deformation, manifesting itself on mesoscopic scales, has been generally recognized. Such progress demanded the development of advanced multiscale modeling frameworks (Ab-Initio, molecular dynamics, discrete dislocation dynamics, strain gradient models, etc.), experimental characterization tools (in-situ TEM, DIC, nanoindentation, micropillar testing, etc.) and analyses of the observed and simulated complex spatiotemporal behaviors, which aim at establishing process–microstructure–property links and bridging gaps from the elementary atomic-scale mechanism, up to the laboratory sample dimension. Progress in the field of plasticity of metals and alloys keeps growing fast and new materials are constantly being developed, concurrently with the emergence of modern processing routes. In parallel, considerable advances are made in the characterization and modeling of microstructures, with an emphasis on setting up a synergy between theoretical and experimental methods. This Special Issue aims at synthetizing recent progress and trends in the area of plasticity of metals and alloys, with a focus on:

  • New approaches to old questions and traditional model materials, to get a deeper understanding of physical mechanisms;
  • New materials and processing routes (high entropy alloys, metallic glasses, severe plastic deformation, additive manufacturing, etc.);
  • Multiscale modeling (atomistic models, discrete dislocation dynamics, strain gradient models, homogenization models, etc.);
  • Experimental characterization methods (HR-DIC, 3D-EBSD, HR-TEM, ECCI, TKD, etc.).

Modeling the Strain-Range Dependent Cyclic Hardening of SS304 and 08Ch18N10T Stainless Steel with a Memory Surface

This paper deals with the development of a cyclic plasticity model suitable for predicting the strain range-dependent behavior of austenitic steels. The proposed cyclic plasticity model uses the virtual back-stress variable corresponding to a cyclically-stable material under strain control. This new internal variable is defined by means of a memory surface introduced in the stress space. The linear isotropic hardening rule is also superposed. First, the proposed model was validated on experimental data published for the SS304 material (Kang et al., Constitutive modeling of strain range dependent cyclic hardening. Int J Plast 19 (2003) 1801–1819). Subsequently, the proposed cyclic plasticity model was applied to our own experimental data from uniaxial tests realized on 08Ch18N10T at room temperature. The new cyclic plasticity model can be calibrated by the relatively simple fitting procedure that is described in the paper. A comparison between the results of a numerical simulation and the results of real experiments demonstrates the robustness of the proposed approach. Full article
