Abstract: The destruction of the bridge structures, etc, most of the time, began with cracks. Application of extended basic theory of finite element method (XFEM) and use of common software abaqus to fracture analysis, a middle beam cracks were concluded in the external loads, and got the stress changes of the artifacts and crack propagation.
