N2 - In this paper the following topics are addressed: (i) the physical meaning of pathindependent integrals for elastodynamically propagating cracks introduced earlier by Atluri, Bui and Kishimoto et al. (ii) the relation of these integrals to the energy release rates, for propagating cracks and (iii) the relation between these integrals and the time-dependent stress-intensity factors KI(t), KII(t) and KIII(t) in general mixed mode dynamic crack propagation. Finally, a new path-independent integral which has the meaning of energy-release-rate for a propagating crack, is introduced.
