| Abstract: | Based on the fully nolinear theory of elasticity, the crack tip field in a rubber-like thin sheet under model-I loading condition is studied.We point out that the deformation near the crack tip is composed of two narrowing regions and one expanding region, and the stress has the singularity R--2nb. |

| Keywords: | Plane stress finite deformation crack tip field |
