As an example of application, the study on small scale shear failure of Al-Zn-Mg-Cu plate under complicated strain and stress states, especially within the plastic zone ahead of a pre-crack, would promote our understanding of the fracture mechanism, of the shielding effect caused by cracking path deflection, and of the mechanism of fracture toughness anisotropy of textured high strength aluminium alloys.

作为一个应用实例，本文关于Al-Zn-Mg-Cu厚板在复杂应力应变状态下的小尺度剪切失效机制的研究，对于了解工业高强变形铝合金的断裂过程、了解裂纹扩展途径偏斜所引起的shielding效应、了解断裂特征和断裂韧度的各向异性等实际问题也是很有启发的。并已被Materi-als Science and Technology认为是&an interesting piece of work containingsome original idea s&。

The results show that the flow stress increases with the increase of the strain rate, and decreases with the increase of the deforming temperature. The saw tooth fluctuation of the flow stress at higher strain rates and lower temperatures indicates the discontinuous dynamic recrystallization. The flow stress of the aluminum alloy during hot compression deformation can be described by using Zener-Hollomon parameter including Arrhenius item, and the deformation activation energy is 176.54 kJ/mol.

研究结果表明：流变应力随应变速率的增大而增大，随变形温度的升高而降低，在高应变速率和较低温度条件下，应力出现据齿波动，呈不连续再结晶特征；该铝合金热压缩变形的流变应力行为可用包含Arrhenius项的Zener-Hollomon参数来描述，其变形激活能为176.54 kJ/mol。
