裂纹区域

The boundary of the crack domain is constructed with the standard Koch fractal curve and the elastic strain energy of the plate is given out by using the perimeter-area relation of the fractal crack domain.

以标准Koch分形曲线构造裂纹的边界，并由分形区域周长与面积的关系推导出平板的弹性应变能。

This kind of damage is called Foreign object damage or simply, FOD. The main form of foreign object damage are notch, avulsion, disjunction and indentation in local regions where produce stress concentration, residual stress , shear bands as well as .

这种外物冲击损伤(Foreign object damage，简称FOD)主要表现为叶片局部区域出现缺口、撕裂、折断和凹坑等，并在局部产生应力集中、残余应力及剪切带、初始裂纹等，给撞击后的叶片寿命带来严重影响。

A craze is a thin platelike region .

小裂纹是一个类似薄片的区域。

In electricity plus thermal group, the pathologic alterations were slighter than model group; there was little crack on the surface of cartilage, with intact collagen fiber structure and less pyknotic chondrocytes. Although some chondrocytes shrank, there were intact cell organs in many chondrocytes even chondrocyte cluster in some regions.

疏密波+热软膜组在病理程度上的改变明显轻于模型对照组，软骨表面裂纹少，胶原纤维结构基本完整，固缩的软骨细胞少，虽可见部分退变的软骨细胞，但部分软骨细胞具有较多的细胞器，某些区域形成软骨细胞簇。

Flash candling is a quality sorting operation which involves searching for several defects: cracks, blood spots, dirt spots, and undergrades, any one of this downgrade the egg quality.

在黑暗环境中，裂纹显示为明亮的线，血斑显示为红色的区域，污垢显示为黑点，蛋黄显示为黑色阴影，其中任何一种缺陷都会降低鸡蛋的品质。

By improving the local structure of the mould, the problem that many porosities and cracks were appeared in the root of blade was solved effectively.

通过对熔模局部区域的结构调整，很好地解决了叶根部位的疏松和裂纹缺陷。

The result indicated that the stress was concentrated on the end of the joint interface and inner filler metal. If brittle intermetallics were produced in these areas, the fracture of joint would occur frequently.

通过采用Marc非线性有限元软件，对接头区在冷却过程中的应力变化、应力分布及裂纹敏感区域等进行了分析。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
