Computational modeling of microstructure [PDF]

open access: yesProceedings of the ICM, Beijing 2002, vol. 3, 707--716, 2003
Many materials such as martensitic or ferromagnetic crystals are observed to be in metastable states exhibiting a fine-scale, structured spatial oscillation called microstructure; and hysteresis is observed as the temperature, boundary forces, or external magnetic field changes.

Microstructure Generation via Generative Adversarial Network for Heterogeneous, Topologically Complex 3D Materials [PDF]

open access: yesarXiv, 2020
Using a large-scale, experimentally captured 3D microstructure dataset, we implement the generative adversarial network (GAN) framework to learn and generate 3D microstructures of solid oxide fuel cell electrodes. The generated microstructures are visually, statistically, and topologically realistic, with distributions of microstructural parameters ...

Learning from 2D: machine learning of 3D effective properties of heterogeneous materials based on 2D microstructure sections [PDF]

open access: yesFrontiers in Metals and Alloys (2022) 1-9, 2023
Microstructure--property relationships are key to effective design of structural materials for advanced applications. Advances in computational methods enabled modeling microstructure-sensitive properties using 3D models (e.g., finite elements) based on microstructure representative volumes.

Creep Characterization of Inconel 718 Lattice Metamaterials Manufactured by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView., 2023
Herein, the creep characteristics of additively manufactured Inconel 718 metamaterials are investigated. The creep behavior of metamaterials and the effects of microstructural defects are assessed, and the microstructure defects are accurately captured using Kachanov's creep damage model.

Ionitronic manipulation of current-induced domain wall motion in synthetic antiferromagnets

open access: yesNature Communications, 2021
Synthetic anti-ferromagnets, where two ferromagnetic layers are coupled anti-ferromagnetically via a spacer, are known for their very large current-induced domain wall velocities.

Conceptual Design and Parametric Optimization of a New Multileveled Horsetail Structure for Bicycle Helmets

open access: yesAdvanced Engineering Materials, EarlyView., 2023
This study aims to explore the feasibility of using a structure inspired by the features of horsetail and human spine as the potential helmet liner, targeting at mitigation of acceleration‐induced injuries. A parametric study is conducted to investigate the effect of individual geometrical variables in the design, indicating its capability to reduce ...

Observation of Néel-type skyrmions in acentric self-intercalated Cr1+δTe2

open access: yesNature Communications, 2022
Here, Saha et al. show that self-intercalation of e2Cr atoms in CrTe2 create an asymmetry in the number of atoms intercalated in the van der Waals gaps between the layers of CrTe2. This inversion symmetry breaking leads to non-collinear spin-textures and

The microstructure of ultrametricity [PDF]

open access: yesJournal de Physique, 1985
The hierarchical organization of the pure states of a S.K. spin glass (ultrametricity) is analysed in terms of self-averaging distributions of local magnetizations. We show that every pure state α defines an ultrametric distance Dα(i, j) among the N sites.
