    • Abstract
  • In this paper, the J integral conservation in adopting the continuum mechanics in the microcrack shielding problems is reexamined. From thetheoretical manipulation as well as the computational experiment, it is proved that there is a redistribution relation of the remote J integral in the microcracking damage region, i.e., the relation of theprojected conservation of the J k vector. In the relation, the J 2 component ignored by Herrmann and Herrmann plays an important role. It is concluded...
