Low order inelastic micromorphic polycrystals [PDF]

Theoretical and Applied Mechanics, 2002
The paper deals with some fundamental issues essential for constitutive modelling of plastic behaviour of metals. Geometric and kinematic aspects of intragranular as well as intergranular plastic deformation of polycrystals are discussed.

Objectives and Key Results–Driven Multiagent Framework for Mechanical Design and Simulation

Advanced Intelligent Systems, EarlyView.
Objectives and key results (OKR)‐agent, an OKR‐driven multiagent framework, turns a plain‐language engineering goal into completed mechanical simulations. Three peer agents—supervisor, modeler, and simulator—share a compact board of OKR and coordinate external molecular dynamics (MD) and finite‐element solvers through a standardized tool interface. The

Photoemission microscope tomography for polycrystalline metals

Science and Technology of Advanced Materials: Methods
We propose a workflow to construct a generative model that provides us with angle-resolved photoemission spectra by utilizing photoemission microscopic measurements on polycrystals, instead of single crystals.

Toward Single‐Crystal Upcycling of Degraded Lithium‐Ion Battery Cathodes

EcoEnergy, EarlyView.
This review first summarizes the degradation mechanisms of polycrystalline cathodes, emphasizing the role of grain boundaries and rock‑salt phase formation. It then highlights the main optimization pathways (surface reconstruction, rapid structural repair, PC‑to‑SC transformation, and interface engineering) and the three conversion methods (SSU, MSAU ...

Finite Element Analysis for Li Batteries at the Mesoscale

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Finite element analysis (FEA), through multi‐physics coupling, has been widely employed to calculate mesoscale structures in LIBs that exhibit inherent randomness and disorder (Figure a). It has been extensively applied to the investigation of critical phenomena such as Li dendrite evolution, Li+ concentration gradients, SEI film growth, particle ...

Thermodynamics of quasi–rate-independent inelastic micromorphic polycrystals [PDF]

, 2009
The paper deals with some new evolution equations for gradient viscoplasticity. Geometric and kinematic aspects of intragranular as well as intergranular plastic deformation of polycrystals are briefly discussed.

Interferometric Vector Piezoresponse Force Microscopy for Simultaneous Ferroelectric Domain and Crystallographic Orientation Mapping in Uniaxial Ferroelectric Polycrystals

Small, EarlyView.
Interferometric vector piezoresponse force microscopy is used to reconstruct crystallographic grain orientations in polycrystalline ferroelectrics directly from local electromechanical response. The approach reveals grain orientation, polarization direction, and domain structure simultaneously, establishing a pathway toward EBSD‐like orientation ...

A continuum model for slip transfer at grain boundaries

Advanced Modeling and Simulation in Engineering Sciences, 2020
Using a continuous representation of dislocations in elastoplastic polycrystals, we investigate slip transfer at grain boundaries by assessing the compatibility of the slip system shear rates with tangential continuity of the plastic distortion rate ...

Microstructural evolution in two-dimensional two-phase polycrystals [PDF]

, 1993
In two-dimensional polycrystals composed of [alpha]-phase and [beta]-phase grains the stability of [alpha][alpha][alpha], [beta][beta][beta], [alpha][alpha][beta] and [alpha][beta][beta] three-grain junctions and [alpha][beta][alpha][beta] four-grain ...
