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]
Lattice configuration of the slip plane in a bcc material. The arrow represents the Burgers vector in this dislocation glide system. Slip in body-centered cubic (bcc) crystals occurs along the plane of shortest Burgers vector as well; however, unlike fcc, there are no truly close-packed planes in the bcc crystal structure. Thus, a slip system ...
The screw component of a mixed dislocation loop can move to another slip plane, called the cross-slip plane. Here the Burgers vector is along the intersection of the planes. In materials science, cross slip is the process by which a screw dislocation moves from one slip plane to another due to local stresses. It allows non-planar movement of ...
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 Burgers material is a viscoelastic material having the properties both of elasticity and viscosity. It is named after the Dutch physicist Johannes Martinus Burgers.

The Burgers vortex sheet is shown to be unstable to small disturbances by K. N. Beronov and S. Kida [9] thereby undergoing Kelvin–Helmholtz instability initially, followed by second instabilities [10] [11] and possibly transitioning to Kerr–Dold vortices at moderately large Reynolds numbers, but becoming turbulent at large Reynolds numbers.
Johannes (Jan) Martinus Burgers (January 13, 1895 – June 7, 1981) was a Dutch physicist and the brother of the physicist Wilhelm G. Burgers. Burgers studied in Leiden under Paul Ehrenfest, where he obtained his PhD in 1918. [1] He is known for the Burgers' equation, the Burgers vector in dislocation theory and the Burgers material in ...
