Keyhole Specimen

Corner to through crack transition in a keyhole specimen

The geometry and loading of the specimen are such that crack growth is planar. The initial corner crack grows and transitions to a through crack in a single analysis. The loading is a constant amplitude cyclic load with Paris crack growth law.
