A circular element centered at the crack tip is constructed. According to the first four terms of Williams stress function, the displacement pattern with singularity is given to the circular element, where unknown parameters are considered as generalized nodal displacements.

A wedge-opening loading (WOL) type of specimen with an instrumented bolt has been developed which can be used to determine the threshold stress-intensity factor Klscc and the crack growth rates daldt at the same time. Strain gages were cemented on the surface of instrumented bolts. During the test,

A stress singularity of type Kr" (6 < 0) exists at the interface corner between bonded elastic quarter planes. The intensity of this stress singularity, referred to here as the free-edge stress intensity factory K,, characterizes the magnitude of the stress state in the region of the interface corne
