Question

If we have the forces btw two parallel edge dislocation ( I and II ) with the same value of Burgers vectors, but

opposite directions. As shown in fig. 2a, the two dislocations are parallel to z axis, with their Burgers vectors along the x axis. The coordinates of the dislocation cores are also shown in the figure

a) Will dislocation I exert a force that may cause dislocation II to glide? Why? Will dislocation I also exert a force that may cause dislocation II to climb?

b) Calculate the force induced by dislocation I acting on dislocation II in the glide plane. Assume that Burgers vectors, shear modulus and poisson's ratio are known.

C) Write procedure and equations that you will use to compute the force induced by dislocation I acting on dislocation II in the glide plane shown in Fig 2 b. the crystal is an isotropic material.
