Some remarks on standard gradient models and gradient plasticity
Mathematics and Mechanics of Solids, 2014 The standard gradient models, originally introduced in the works of Gurtin ( Physica D 1996; 92: 178) and Frémond and Nedjar ( Int J Solids Struct 1996; 33: 1083) have been studied intensively in the last few decades for various applications in plasticity, damage mechanics and multi-phase analysis.

Advanced Engineering Materials, EarlyView.Laser powder‐bed fusion (L‐PBF) can produce dense WE43 magnesium alloy parts, but their mechanical properties are limited by a nonhomogeneous microstructure. This study investigates the effects of varying direct aging (T5) and artificial age‐hardening (T6) conditions on microstructure and strength. Optimized T6 treatment significantly improves strength

A Truly Sparse and General Implementation of Gradient-Based Synaptic Plasticity [PDF]
arXivOnline synaptic plasticity rules derived from gradient descent achieve high accuracy on a wide range of practical tasks. However, their software implementation often requires tediously hand-derived gradients or using gradient backpropagation which sacrifices the online capability of the rules. In this work, we present a custom automatic differentiation

A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams
Advanced Engineering Materials, EarlyView.The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.

Strain gradient plasticity, strengthening effects and plastic limit analysis
International Journal of Solids and Structures, 2010 AbstractWithin the framework of isotropic strain gradient plasticity, a rate-independent constitutive model exhibiting size dependent hardening is formulated and discussed with particular concern to its strengthening behavior. The latter is modelled as a (fictitious) isotropic hardening featured by a potential which is a positively degree-one ...

Impacts of Device Geometry and Layout on Temperature Profile during Large‐Area Photonic Curing
Advanced Engineering Materials, EarlyView.The study investigates how gate geometry affects peak curing temperature during photonic curing of solution‐processed indium zinc oxide thin‐film transistors. Using 3D simulations and experimental validation, it reveals that larger gate areas and smaller aspect ratios increase curing temperature and thus improve transistor performance. Findings provide

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics
Advanced Engineering Materials, EarlyView.Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

Advanced Engineering Materials, EarlyView.This study reports for the first time the mechanical properties of brazed joints featuring Additively manufactured parts, such parts will likely need to be joined or combined with other components, and brazing offers a way of doing this for complex shapes without distortion. A new shear test methodology developed for such joints is also described.
