The elastic range, the plastic range (during which the material flows at a constant stress), the strain-hardening range, and the range during which necking occurs, terminating in fracture.
弹性范围，塑料范围（当材料以不变的应力流动时），应变硬化范围和发生颈缩现象以其断裂终止的范围。

Kinematic hardening model was used in FEM analysis and the response behaviors of transient local stress strain for material was also considered.
有限元分析采用了随动强化模型，并考虑材料瞬态局部应力应变的响应特性。

The exact solution of linear elastic fracture mechanics is suggested in this paper and the plastic zone of crack tip is calculated under the condition of strain-hardening of material.
