โฆ Synopsis
Abs~act-"Path-independent" integrals are presented for use in fracture dynamics. One class of integrals is based on a reciprocal theorem and the other is related to the energy flow into a moving crack tip. These integrals may be used to numerically calculate the dynamic stress intensity factor in elastodynamic crack propagation problems. Several examples are presented using the release node technique to model crack propagation.

In this paper the properties of eigenfunction expansion form (abbreviated as EEF) in the crack problems of plane elasticity and antiplane elasticity are discussed in details. After using the Betti's reciprocal theorem to the cracked body, several new path independent integrals are obtained. All the
This paper presents the three-dimensional path-independent integrals which are physically the energy release rates per unit area of crack extension along the direction of crack propagation in the volume surrounding the crack front increment for thermoelastic fracture problems. The variation of the i
