缺口

The results of the tests indicate that the spots where the fatigue short cracks initiated are at the bottom surface of the circle indention and some disfigurement places in that surface. The propagation paths of the cracks are very complex and the decentralization of the obtained data is very severe due to the micro organism of the material. While the distribution of the short fatigue cracks exist self-regularity on their length, angle, density and expansion rate of the cracks, which are less affected by the outer factors.

试验中观察到短裂纹形状多为Z型，试验结果表明疲劳短裂纹往往萌生于试样缺口底部表面和缺口表面缺陷处，其扩展复杂，路径曲折，数据分散性大，强烈地受材料微观组织的影响，疲劳短裂纹在长度、角度、密度和扩展速率方面虽数据分散但具有自身的规律，受外部因素的影响较小。

Based on the fundamental principles of the improved method mentioned above, multi-functional computation software package, which can be used to analyze effectively the interference effects of random flaws in plane problem, boundary problem and space problem, is compiled and a number of problems involved in the interference effects of different kinds of flaws such as random equal length through-cracks, random branched throughcracks, random unequal length through-cracks, random holes to through-cracks, unequal length edge cracks, equal length and distance multiple edge cracks, random notches with different aspect ratio, random notch to edge crack, non-coplanar surface cracks with different aspect ratio, staggered surface cracks, surface crack to embedded crack and embedded cracks near free boundary are analyzed and computed by the package.

依据上述改进法的基本原理，本文编制了能有效地分析平面问题，边界问题及空间问题的任意缺陷群相互干涉效应的多功能计算软件包。据此，本文分析计算了各类缺陷群。诸如，任意等长裂纹群。任意折裂纹群；任意不等长裂纹群，任意孔与裂纹群，不等长边裂纹群。等长等间距多裂纹群，任意形状比缺口群，任意缺口与边裂纹，非共面不同形状比表面裂纹群，交错型表面裂纹群，表面裂纹与埋藏裂纹群及自由边界附近埋藏裂纹群等的相互干涉效应问题。

POM is easy to form big spherical crystals due to its regular chain structure, resulting in low notched impact strength, sensitive to notch. On the other hand, POM is incompatible with most modifiers and difficult to be modified.

但聚甲醛分子链结构规整，无侧基，易结晶，形成大球晶，缺口敏感，缺口冲击强度低，韧性差，且与其它改性剂相容性差，难以增韧。

The strain rate field below notch root of the charpy V-notched specimen was numerically simulated using a dynamic elasto-plastic finite element method.
