Substitutional Alloying Using Crystal Graph Neural Networks

1 code implementation19 Jun 2023 Dario Massa, Daniel Cieśliński, Amirhossein Naghdi, Stefanos Papanikolaou

Materials discovery, especially for applications that require extreme operating conditions, requires extensive testing that naturally limits the ability to inquire the wealth of possible compositions.

Direct detection of plasticity onset through total-strain profile evolution

no code implementations8 Jul 2021 Stefanos Papanikolaou, Mikko J. Alava

Plastic yielding in solids strongly depends on various conditions, such as temperature and loading rate and indeed, sample-dependent knowledge of yield points in structural materials promotes reliability in mechanical behavior.

Learning crystal plasticity using digital image correlation: Examples from discrete dislocation dynamics

no code implementations24 Sep 2017 Stefanos Papanikolaou, Michail Tzimas, Andrew C. E. Reid, Stephen A. Langer

Digital image correlation (DIC) is a well-established, non-invasive technique for tracking and quantifying the deformation of mechanical samples under strain.
