The Burgers vector will be the vector to complete the circuit, i.e., from the start to the end of the circuit. [2] One can also use a counterclockwise Burgers circuit from a starting point to enclose the dislocation. The Burgers vector will instead be from the end to the start of the circuit (see picture above). [3]
The arrow represents the Burgers vector in this dislocation glide system. Slip in face centered cubic (fcc) crystals occurs along the close packed plane . Specifically, the slip plane is of type {111} , and the direction is of type < 1 10>.
The yellow plane is the glide plane, the vector u represents the dislocation, b is the Burgers vector. When the dislocation moves from left to right through the crystal, the lower half of the crystal has moved one Burgers vector length to the left, relative to the upper half. Schematic representation of a screw dislocation in a crystal lattice.
A dislocation can be characterised by a vector comprising the distance and direction of relative movement it causes to atoms as it moves through the lattice. This characterising vector is called the Burgers vector and remains constant even though the shape of the dislocation may change or deform. [citation needed]
The phenomenological equation which describes Harper–Dorn creep is = where ρ 0 is dislocation density (constant for Harper–Dorn creep), D v is the diffusivity through the volume of the material, G is the shear modulus and b is the Burgers vector, σ s, and n is the stress exponent which varies between 1 and 3.

A vector made from two Roman letters describes the Burgers vector of a perfect dislocation. If the vector is made from a Roman letter and a Greek letter, then it is a Frank partial if the letters are corresponding (Aα, Bβ,...) or a Shockley partial otherwise (Aβ, Aγ,...). Vectors made from two Greek letters describe stair-rod dislocations.
Flip over and place a piece of gouda on each patty. Cook for another 2 to 3 minutes, until the burgers reach desired doneness and the cheese has melted. Remove from heat and let rest. Using a pastry brush, butter both sides of the brioche buns with the melted butter. Toast on the grill for 1 to 2 minutes before assembling the burgers.
