Abstract:

Two radial cuts are made in a disc-shaped solid, the wedge or sector thereby produced is removed, and the exposed faces of the radial cuts are forced into contact with each other. By bonding or welding together the faces of the radial cuts, a self-stressed disc, capable of propagating a pure mode 1 crack, is created. Author
