Determine the shear strain

  1. May 26, 2016 #1
    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?
