http://mf.grsu.by/UchProc/DJVU/Math/Math/Math/Physics/02 WebbThe aim of this paper is to develop a dynamic theory of dislocations more systematically which makes use of the concepts of ﬁeld strengths, excitations and constitutive relations. This theory is a kind of axiomatic ﬁeld theory of dislocations. The nature of such a general dislocation theory is geometrically nonlinear.

WebbA dislocation is a linear crystallographic defect or irregularity within a crystal structure which contains an abrupt change in the arrangement of atoms. The crystalline order is restored on either side of a dislocation but the atoms on one side have moved or slipped.
