Here is another kind of dislocation, called a screw dislocation. Repeat the experiment of applying a shear force to see:
beta is the shear force constant between atoms in different rows. How do the structure of the dislocation and the shear force required for motion vary with beta over the range 2 to 20? (You can drag the slider beyond the end of its range.)
(To make a screw dislocation, drag an arrow vertically in the array with the RIGHT mouse button. See Special features for more information.)
