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 ...
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 ...
ACCORDING to the theory of Burton, Cabrera and Frank 1, crystals can only grow at supersaturations too low for two-dimensional nucleation, when dislocations are present. Where a screw dislocation ...
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 ...
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 ...
