| Abstract: | The elastostatic field near the interface crack tip between two incompressible materials is analyzed with the fully nonlinear theory. By dividing the crack tip field into shrinking and expanding regions, the asymptotic equations for the crack tip field are derived and solved. The singularities of stress and strain near the crack tip are revealed. |

| Keywords: | incompressible material plane strain condition crack tip field fully nonlinear theory |
