Abstract A study is presented of the stress inside a two-dimensional elastic solid which has a boundary surface angle and which is loaded by an internal point source of expansion. An exact analytic solution for the stress is obtained, for general surface angle and source position, and evaluated numerically for several representative cases of wedges and notches. The singular behaviour given by the leading terms near the angle vertex is found to be highly localized, and there is little or no stress enhancement near the source. For many combinations of boundary angle and source location, however, a local region of significant enhancement occurs on that part of the surface nearest the source. Implications of these results are discussed, with particular reference to surface steps.
