โœฆ Synopsis

General expressions of the crack-tip fields for a dynamically extending crack through an anisotropic elastic material are given. Based on the crack-tip fields, the associated dynamic energy release rate is also derived. Explicit results are given for transversely isotropic materials.

An expression for the energy flux into the tip of an extending crack in terms of the dynamic elastic field of the crack is derived on the basis of an overall energy rate balance. It is shown that the energy flux depends only on the near-tip elastic field. The expression is compared to other expressi

16MnR steel has been investigated experimentally and numerically to explore the microstructural change in the crack tip zone. It was found that, under an applied load, carbon atoms near the crack tip diffused in the gradient direction of stress, strain and temperature fields into the crack tip zone,
