| Abstract: | Using the finte element method mixed in different areas, the writer analysed horizontal cracks in arch dams. The feature of this method is spplying a queer stress element at the end of the crack and common displacement elements in the other areas. Then on the basis of the energy principle mixed in different areas the writer established a linear algebraical equation set, where the intensity factors of the crack and the displacements of element nodes are unknow. |
