A seemingly novel integral equation approach is presented for the analysis of propagating fractures in plane
regions, The crack is modelled by a continuous distribution of Edge Dislocations. Arbitrary distributions of both free
field stresses and internal tractions on the crack surfaces are accounted for and the governing equations are derived
assuming homogeneous, isotropic, elastic-brittle material behaviour. A fundamental feature of this approach is that only
geometrical information describing the shape and the size of the fracture is necessary. This allows one to easily generate
the additional geometrical data for the propagated portions of the crack with negligible effort. A simple technique for
numerical solution is outlined, and the results obtained by analyzing a series of nongrowing and propagating fractures
are discussed.
