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 ...

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 ...

As the aerospace sector pursues propulsion systems that are cleaner, quieter, and more efficient, materials used in turbine components face increasingly demanding thermal and mechanical environments.

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 ...
