Abstract: 

This paper outlines a simple technique for introducing displacements of discontinuities into finite element computations. This method considers displacement discontinuities existing in a continuum and could be easily added to available elastic codes. The modification induced by this technique can be contained in the load vector, so that the stiffness matrix is not altered. Besides, this method does not increase the number of degrees of freedom and, no net forces or moments are induced on the finite element mesh either.
