Abstract
A powerful method is described for determining stress intensity factors for plane cracks intersecting a free edge and where the bulk stress field is such that the crack faces are pressed together along at least part of their length. This configuration occurs widely in problems where the crack is propelled by a contact stress field, but the simpler example given here for illustration purposes involves a cracked column undergoing compression and shear.Keywords
