The results show that fatigue crack began to initiate at an interior inclusion at about 5%-10% of fatigue lifetime, and then many micro-cracks formed dispersively due to the decohesion of spherical carbide around the inclusion from the matrix, which will grow and coalesce each other with fatigue processing.

这种现象被认为是由于材料内部存在的非金属夹杂物引起的闭。目前的长寿命疲劳设计是以材料或结构在1护次应力循环的实验数据为基准的，而机器和结构承受1丁以上交变载荷的情况并不少见[3]。

The prior cycles with higher axial stress and larger strain range greatly restrains ratchetting strain of subsequent cycling with lower ones. Creep behavior plays an important role in the ratchetting strain and its influence on ratchetting behavior can not be neglected. Fracture morphology characteristics of two kinds of materials were investigated by scanning electron microscope. It shows that failure of material A is induced by cavitation and that of material B is induced by decohesion. For material A, with the decreasing strain amplitude the fracture surface shows more larger diameter globular particles under uniaxial loading and can be seen more obvious and deep crack under multiaxial loading. However for material B, with the decreasing strain amplitude fracture surface shows larger and larger scalelike shape and becomes more smooth under uniaxial loading, but fracture surface under multiaxial loading looks like more smooth than that of uniaxial loading, and shows gradually wave-like morphology.

通过扫描电子显微镜研究表明：材料A为空穴引起的失效，材料B为剥离导致疲劳破坏；随着载荷幅值的减小，材料A在单轴载荷下，断口表面浮出更多更大直径的球状颗粒，而多轴载荷下，可以看到很深的裂纹；随着载荷幅值的减小，材料B在单轴载荷下，断口表面鱼鳞片越来越大，表面越来越平整，而多轴载荷与单轴载荷相比，断口表面看上去更加平整，并且随着载荷幅值的减小，断口逐渐呈现波浪形貌；通过微观的傅立叶变换红外光谱分析，结果表明随着应变幅值的增加，无论载荷是单轴还是多轴状态下，橡胶材料吸光度比值随着幅值的增加而增加，这说明体系中的结晶含量也随之增加。

You may be proud that not the smallest beam in the slightest crack of space will get in your deflector shield eye booth, but you look like a bug on hind legs.

" "你可能会感到自豪的是，并不是最小的束在丝毫裂缝的空间将得到在您的导流盾牌眼摊位，但您看起来像一个bug对后腿。

With the increase of Al_2O_3 content, the TiB_2 grains are smaller and the deflexion of crack expanding increases.

对材料韧性的研究结果表明，随着Al_2O_3含量的增加，TiB_2晶粒的细化，裂纹的扩展偏转增多。

And some important phenomena which is very different from the stiff interface such as the interface debonding and sliding, crack defluxion, fiber bringing and pulling out have been successfully reproduced and revealed in the case of soft interface, accompanied result of acoustic emission is also presented.
