Fast crack growth along interfaces Academic Article

abstract

• Analyses of dynamic crack growth along interfaces are discussed. The material on each side of the bond line is characterized by an elastic constitutive relation. A cohesive surface constitutive relation that allows for the creation of new free surface is also specified across the bond line. The resistance to crack initiation and the crack speed history are then predicted without invoking any additional failure criterion. Two dimensional models, both plane strain and plane stress, of the configuration used in experiments of Rosakis and co-workers are analyzed. The focus is on the emergence of crack speeds greater than a characteristic wave speed and on the nature of crack tip fields at such intersonic crack speeds.
