| Abstract: | A finite element method which is a variable stiffness method combined with the initial stress method is developed on the basis of the theory of plastic deformation. The method is used in the analysis of the elastic-plastic crack tip field of cracked tension plate with or without edge stiffeners. The effects of stiffeners on elastic-plastic fracture of cracked plates are analysed. The validity of the results of linear elastic fracture analysis, when the plastic region exists, is discussed. |
