| 摘 要： | 利用动态强度理论讨论了一维剥离破坏,得到了下列结论:对于均匀材料,断裂处会有一定的宽度,也即有一定的构造性.对于剥离破坏,利用物质损伤破坏的动态理论,利用密度准则,对物质损伤演化及破坏过程进行了描述,并与混沌动力学中从混沌到有序的倒分叉过程进行了比较.

| 关 键 词： | 时间特征 一维剥离 构造性 密度准则 倒分叉过程 |

| Abstract: | This paper deals with one dimensional spallation fracture of solid, taking consideration of time characteristic, and reaches a conclusion that fracture may be concentrated in definite width, i.e fracture has structure. As for the spallation fracture the paper describes the evaluation process of damage and fracture by making use of kinetic theory of damage and fracture and compares it with the backward bifurcation process of chaotic dynamics. |

| Keywords: | time characteristic one dimensional spallation structure of fracture concentration criterion backward bifurcation |
