Two dislocation lines parallel to z-axis lying in the x-z plane are shown in the figure. The glide force (in Newton) exerted by the edge dislocation on the screw dislocation is: _______ (round off to nearest integer).
For the edge, the shear stress component is given by:
τxy = (Gb / 2π(1 - ν))(x(x2 - y2) / (x2 + y2)2)
Given: Shear modulus, G = 28 GPa Poisson's ratio, ν = 0.3 Burgers vector, b = 0.29 nm Distance between the two dislocations = 0.5 nm
τxy = (Gb / 2π(1 - ν))(x(x2 - y2) / (x2 + y2)2)
Given: Shear modulus, G = 28 GPa Poisson's ratio, ν = 0.3 Burgers vector, b = 0.29 nm Distance between the two dislocations = 0.5 nm
