In-plane solutions are given for the order of the stress singularity a
t an internal point in an elastic, isotropic solid where three wedges
of different materials meet. The three interfaces are either all perfe
ctly bonded or a disbond is introduced along one interface. One featur
e of this three-material junction that is not present for the correspo
nding two-material case, is that each interface is geometrically diffe
rent and, therefore, the singular behavior is dependent on which inter
face is disbonded. Each material and geometrical combination therefore
gives rise to four problems, one with perfect bonding at all interfac
es, and three cases of an interface disbond. Numerical results are pre
sented for selected three-material junctions. New results for two-mate
rial junctions and wedges that serve as special cases for the present
study are also presented.
