The relaxed state of a type of topological defect (screw dislocation) located in a dispersive (non-local) elastic solid is discussed from a viewpoint of gauge field theory. The starting point of this ...

Introducing solute into a crystalline lattice is a known approach for strengthening materials; solute atoms cause localized lattice strain, making the passage of a dislocation more difficult. It is ...

Dr. Edwin L. Thomas, professor in the Department of Materials Science and Engineering, and a team of researchers from Texas A&M University and Yonsei University recently discovered a helicoidal-shaped ...

NEW YORK — Results presented at the American Shoulder and Elbow Surgeons Annual Meeting showed button fixation had a significantly greater risk of recurrent shoulder dislocation but lower reoperation ...

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 ...

Recently, a research group developed a giant magneto-superelasticity of 5% in a Ni34Co8Cu8Mn36Ga14 single crystal. This was achieved by introducing arrays of ordered dislocations to form ...

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 ...
