Zero thickness crack tip interface elements for a crack normal to the interface between two materials are presented. The elements are shown to have the desired r\*-' (0 < I < 1) singularity in the stress field at the crack tip and are compatible with other singular elements. The stiffness matrices o

## Us&act-It is shown that the singularity of stresses near the tip of crack in an elastii: bi-material can be obtained by using degenerate triangular elements, the shape functions of which are derived from those classical isoparametric elements. A four node triangular element is tested on two dif
