Mesoscale crystal plasticity modelling of Cu-Nb nanolaminates composites considering nonlocal effects and confined layer slip mechanisms

Materials & Design
Nanolaminated materials have garnered considerable attention due to their high strength, elevated strain hardening rate, and measurable plasticity. The heightened strain hardening rate is attributed to the presence of back stress resulting from plastic ...

Proposition of a New Translation Rule in Kinematic Hardening

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1980
The translation rule in the so-called kinematic hardening model with respect to elasto-plastic constitutive relations of metal is investigated. The representative translation rules of Prager's and Ziegler's type and of the stress increment type and of the stress increment type which was proposed by the author in the past are pointed out to have some ...

Nonlinear kinematic hardening under non-proportional loading [PDF]

, 1979
Nithin the framework of conventional plasticity theory, it is first determined under which conditions Helan-Prager's and Ziegler's kinematic hardening rules result in identical material behaviour.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Bree's diagram of a functionally graded thick-walled cylinder under thermo-mechanical loading considering nonlinear kinematic hardening

Case Studies in Thermal Engineering, 2018
In this paper, elasto-plastic analysis of a thick-walled cylinder made of functionally graded materials (FGMs) subjected to constant internal pressure and cyclic temperature gradient loading is carried out using MATLAB.

Weaving Intelligence: Thermally Drawn Multimaterial Fibers Toward AI‐Enabled Smart Textiles

Advanced Materials, EarlyView.
Thermally drawn multimaterial fibers are rapidly advancing as intelligent structural units for next‐generation smart textiles. Integrating multimaterial architectures with neuromorphic and spiking‐neural‐network principles enables fabrics that can sense, compute, and adapt autonomously.

All‐Polyimide‐Mediated Liquid Metal Assembly on Aerogels for Breathable and Robust Electronic Skins

Advanced Materials, EarlyView.
An all‐polyimide‐mediated assembly strategy resolves the fundamental conflict between physiological breathability and electromechanical robustness in wearable electronics. By integrating a polyamic acid‐encapsulated liquid metal ink onto an ultralight polyimide aerogel, imidization‐induced contraction enables low‐temperature conductive activation and ...
