| Abstract: | In this paper,the basic physical characteristics of the damageblunting mechanism on the crack tip about polymers are described on the basis of the constant observation to the process of the crack propagation under the SEM.The damage evolution in the viscoplastic zone on the crack tip is deduced and the damage crack model about polymers is constructed. |
