| Popis: | A finite deformation analysis of crack tip fields in a plane strain center cracked panel specimen is performed by taking the nucleation and growth of microvoids into consideration. It is shown that, even when the stress distribution deviates from the HRR singular field and the J-based characterization of crack tip region is not ensured, there exists a stress strain field characteristic of a blunted crack in the immediate vicintity of crack tip. This result suggests that the J-integral with an appropriate integrating path can characterize the stress strain field near a blunted crack tip and can be a fracture mechanics parameter in very large scale yielding. |
