Fracture predictions based on a coupled chemo-mechanical model with strain gradient plasticity theory for film electrodes of Li-ion batteries

Engineering Fracture Mechanics, 2021
High-capacity electrodes in Li-ion batteries inevitably undergo a large volume deformation originating from high diffusion-induced stresses during charging and discharging processes.

The tension-compression behavior of gradient structured materials: A deformation-mechanism-based strain gradient plasticity model

, 2021
Gradient structured (GS) metals can simultaneously achieve high strength and high ductility, which is the pursuit of structural materials. Abundant studies have pointed out that significant kinematic hardening is key to their strength-ductility ...

Rethinking Gradient Projection Continual Learning: Stability/Plasticity Feature Space Decoupling

Computer Vision and Pattern Recognition, 2023
Continual learning aims to incrementally learn novel classes over time, while not forgetting the learned knowledge. Recent studies have found that learning would not forget if the updated gradient is orthogonal to the feature space.

A modified Johnson-Cook material model with strain gradient plasticity consideration for numerical simulation of cold spray process

, 2020
Owing to the low processing temperatures and subsequent minimal thermal residual stresses, cold spray (CS) process has significant potential as a fabrication route for freeform components, thus making it a prospective additive manufacturing technology ...

Plastic axial gradient-index lens

Applied Optics, 1985
An axial gradient-index (GRIN) lens, where the refractive index varies along the optical axis of a convex lens, can reduce the spherical aberration compared with the conventional homogeneous lens. The transparent plastic axial GRIN material was successfully fabricated by chemical copolymerization and diffusion techniques.

Evolution of the length scale in strain gradient plasticity

International journal of plasticity, 2019
An equivalence is assumed between a microstructural length scale related to dislocation density and the constitutive length scale parameter in phenomenological strain gradient plasticity.

On standard gradient plasticity and visco-plasticity

International Journal of Solids and Structures, 2021
Abstract This paper is devoted to the standard theory of gradient plasticity and visco-plasticity, cf. Gudmundson (2004), Fleck and Willis (2009) and the quoted references. Within the framework of the generalized standard materials and the generalized principle of virtual work, our attention is focussed on the mathematical basis of the theory in ...

Some forms and properties of models of strain-gradient plasticity

Journal of the mechanics and physics of solids, 2019
A fairly general formulation for rate-independent strain-gradient plasticity is studied. It includes the possibility of both “energetic” and “dissipative” higher-order stresses and a general effective plastic strain-rate E ˙ , which is convex and ...
