Abstract
Singularity fields at the tip of a crack running dynamically along the interface between two anisotropic solids are extracted from the analytical solution. The dependence of the oscillatory index and the energy factor on the crack speed v stimulates new concepts on interfacial fracture mechanics, especially in the range close to the lower Rayleigh wave speed. The interlayer fracture model clears several ambiguities caused by a mathematically sharp interface, such as the judgement of crack tip contact, the near tip mode mixity, the dynamic arrest of a running interfacial crack, and the dislocation emission from the interface crack tip.
