The motion of dislocations in response to stress dictates the mechanical behaviour of materials. However, it is not yet possible to directly observe dislocation motion experimentally at the atomic ...

where b is the Burgers vector and D is the inter-dislocation spacing. · For the tilt boundary shown, the dislocations are straight edge type. For a pure twist boundary, an array of screw dislocations ...

Researchers recently discovered a helicoidal-shaped defect in layered polymers, uncovering how solvents can diffuse through layers and produce color changes. Dr. Edwin L. Thomas, professor in the ...

Bruno Oliveira Cattelan from ACH team participated at the AI Day 2023 with a poster presentation on the preliminary result of their machine learning work applied to material research. participated at ...

Jogs and kinks are atomic scale changes in direction of a dislocation line. Jogs are out of the slip plane and kinks lie in the dislocations slip plane. For the edge dislocation shown, the jogs are of ...

Miniature plates and screws can be used to provide fixation for unstable proximal interphalangeal joint dorsal fracture dislocations — but at the risk of complications, according to researchers in ...
