| Abstract: | J-Integration plays an important role in the elastic-plastic fracture mechanics, determins the characteristisc of the crack point field and takes significant position for determining the development of craks. This paper deals with the finite element numerical method of J-integration as well as interaction J-integration and also discusses thr method for extracting stress-strength factors, with some computational examples prensent-ed. |
