| Abstract: | The crack fault on the barrel suporting shell of crane was dynamically imitated applying finite element analysis method and theory of fracture mechanics. The posiono of crack extension,tearing angle and appearence of fracture were aquired. The conclusion indicates that applying this method to reappear the crack extention process of structure is feasible. |
