24 Strain Relaxation in Thin Films

24.1 Dislocation Array Beneath the Free Surface

Consider an infinite array of dislocations with uniform spacing p at a distance h below the free surface of a semi-infinite body (Fig. 24.1). The stresses due to this array at an arbitrary point can be obtained by superposition of stresses due to each dislocation alone. Of particular importance for the subsequent energy analysis are the stress components σxy, σyy, and σzy. These are derived by Lubarda (1998) as
