โฆ Synopsis
The Eshelby tensor E has vanishing divergence in a homogeneous elastic material, whereas the invariance of the crack tip J integral suggests, in accord with known solutions, that the product rE will have a finite limit at the tip. Here r is distance from the tip. These considerations are shown to lead to two general integrals of the equations governing singular crack tip deformation fields. Some of their consequences are discussed for analysis of crack tip fields in linear and nonlinear materials.

The theoretical foundation for nonlinear fracture mechanics is the two-dimensional J-integral [1][2][3]. It is defined for a small-strain, nonlinearly elastic material in terms of a contour integral. Through an asymptotic analysis, the J-integral has been shown to characterize the intensity of the n
Certain finite element methods for characterizing crack tip fields, stress intensity factor, and energy release rate for problems formulated in the context of linear elastic fracture mechanics have been applied in the analysis of a nonlinear hyperelastic material, including large deformation effects
