Special Issue Information
Pronouncements in recent years about the lack of progress in understanding metal plastic strain hardening that occurs between yielding and fracturing do not fully correspond with subsequent research reports made on the subject. The stated lack of progress after Taylor’s model description of a parabolic stress–strain curve will be refuted in the present Special Issue update on “Metal Crystal/Polycrystal Plastic Strain Hardening”. Post-Taylor considerations of interest include but are not limited to the nature of deformation-induced point defect production, a role for partial dislocation/stacking fault characterizations, dislocation intersections/reactions, dislocation group dynamics, and dislocation pile-up/grain boundary obstacle associations. Strain hardening roles in stress–strain, fatigue, and hardness tests, in the latter case especially involving nano-indentation hardness testing, are to be characterized and correlated with corresponding constitutive modeling of plasticity/hardening and computational simulations of metal behaviors. Particular attention is given to the several sub-topics of metal processing via severe plastic deformation, the evolution of micro- and nano-scale structures and strength levels, and to additive metal manufacturing methods.
Contributions describing experiments, theory, and/or numerical simulations are all welcome. Techniques can involve one or more length/time scales. For example, modeling can include DFT, molecular dynamics, discrete dislocation dynamics, phase field methods, continuum dislocation theory, anisotropic single/polycrystal crystal plasticity, strain gradient theory, and/or macroscopic continuum plasticity. Time scales can range from very long (e.g., quasi-static indentation, fatigue) to very short (e.g., shockwaves and impact). Regarding constitutive modeling, classical analytical and emerging machine learning-driven approaches are of interest. In any case, papers will include some aspects related to the keywords, most notably plastic yielding and strain hardening in crystalline solids, as evidenced by the title of this Special Issue.
