The Interface Crack

摘要: It is known that oscillatory singularities appear in problems involving interface cracks are assumed to have open tips. An unsatisfacory aspect of the they lead overlapping crack faces. The a tension field, originially treated by England among others, thus reconsidered on basis not completely and its faces frictionless contact near formulation leads pair coupled singular integral equations. singularities, no longer oscillatory, exhibit some unusual features indicate spreading field intimately connected with failure shear. A new stress-intensity factor obtained compared factors for crack. /Author/
