| 摘 要： | First the deviator strain energy is introduced, then the problem of plane-crack critical growth was discussed, a path independent line integral J^* was defined, furthermore its conservation was proved strictly. As application examples, Mode-Ⅰ stress intensity factors of cracked beams were obtained with present approach. The results are shown to agree well with those available in the open literature.

| Abstract: | First the deviator strain energy is introduced, then the problem of plane-crack critical growth was discussed, a path independent line integral J* was defined, furthermore its conservation was proved strictly. As application examples, Mode-I stress intensity factors of cracked beams were obtained with present approach. The results are shown to agree well with those available in the open literature.
