The "line tension" T in a curved dislocation segment has a magnitude T = Gb. What level of applied shear stress t is required to maintain the dislocation segment shown below at a radius of curvature of R? (HINT: The length of dislocation line e in a circular arc is given by e = RO.) T R T = y T F dislocation line The "line tension" T in a curved dislocation segment has a magnitude T = Gb.
