【Abstract】 Present situation and development of application of FEM in elasticity fracture mechanics (FM) are presented in this paper to discuss about the disposal methods of singularities existed in crack tip. What is reviewed systematically and chronolagically is something about historical development and researching achievement gained by a number of scholars in various countries. And imitating and disposing method of singularities are also evaluated. It can be used to help scholars and technicians in this field with further research and proper choice of methods.更多还原
