I don't know how to solve this kind of problem:
Given a crystal and its volume V. This Crystal is subjected to a shear stress making a slip plane (h k l ) in a slip direction [h k l]. Given also the lattice parameter a and slip plane spacing L, and the edge dislocation a/2 that passed halfway through the crystal on every fourth plane.
The question is what is the shear strain?
So to solved this problem i used this equation
y(shear strain) = pbX
p= dislocation density, b =burger vector, and X= average dislocation
where p = L/V and b =a/2
my problem is how to compute X?
