THE INTERACTION OF DISLOCATIONS AND PLANAR FAULTS IN SOLIDS

The equilibrium configurations of an array of straight parallel dislocations and planar defects bounded by dislocations in a solid are considered. On the basis of dimensional arguments and using Euler's theorem for homogeneous functions, it can be shown that the total internal surface energy of the planar defects is constant for all possible unrestrained equilibrium configurations of the array and is equal to the sum of all pre-logarithmic interaction energy factors.
