Mechanical analogy of long Josephson junction

The new mechanical analogy of long Josephson junction are considered. It set, that behaviour of a magnetic field in long Josephson junction are analog a behaviour an elastic rod under a buckling Thus, a critical magnetic field of transition from Meisner's states in the mixed are analog of the Eulerian threshold losses of stability for an elastic rod Besides it is shown, that vortexes of a magnetic flux penetrating into the one-dimensional junction are analog of a line of spins in an external field which orientation depends on a relation of a natural and exterior magnetic field, i. e. long Josephson junction can be considered as dynamic domain structure.
