Firstly, the equation for stress intensity factors under static uniform pressure is used as the reference case, and then the weight function for a thick-walled cylinder containing a radial edge crack can be worked out. Secondly, the dynamic stresses in uncracked thick-walled cylinders are solved under internal impulsive pressure by using mode shape function method. The solution consists of a quasi-static solution satisfying inhomogeneous boundary conditions and a dynamic solution satisfying homogeneous boundary conditions, and the history and distribution of dynamic stresses in thick-walled cylinders are derived in terms of Fourier–Bessel series. Finally, the dynamic stress intensity factor equations for thick-walled cylinder containing a radial edge crack subjected to internal impulsive pressure are given by dynamic weight function method.
首先采用静态内压下的应力强度因子作为参考解，得到了带径向边裂纹厚壁圆筒的权函数；然后用振型函数方法推导无裂纹厚壁圆筒在冲击内压下的动应力响应，分析中将相应的弹性动力学方程解分为满足非齐次边界条件的准静态解和满足齐次边界条件的动态解的叠加，利用傅立叶-贝塞尔级数展开，推导出了厚壁圆筒内动应力的响应历程和分布规律；最后由动应力权函数方法导出带径向边裂纹厚壁筒在冲击内压下的动态应力强度因子计算公式。

The micro mechanism considers that the inclusion in material, called micro defect crack, is the nucleus of internal crack initiation, interaction, between the stress field of the micro defect crack tip as loading and strain field of crystal lattice caused by crystal point passim (as vacancies or interstitial atom, H, O, N et al), will trap the point passim, and cause the enrichment of point passim around the micro defect crack.
其中疲劳裂纹内部萌生的核心是材料中的第二相粒子、夹杂物或微空洞，称为微裂纹；而微裂纹的长大是材料中间歇原子或空位等点缺陷在微裂纹尖端富集沉淀的过程，微裂纹的长大速率受到点缺陷富集扩散速率和疲劳载荷的双重影响。

It is suggested that this defect is originated from the internal crack and the subcutaneous bubble s of billet,as well as unreasonable pass design of roughing mill.
通过对试样进行金相分析，对铸坯表面修磨试验结果分析及对连铸坯在高线粗轧第1道和第2道轧制的受力和变形的分析，发现盘条表面的一种特殊的线状缺陷形成的原因是连铸坯存在边内裂和皮下气泡，粗轧机组(特别是第1和第2架)孔型设计不合理，也促进这种线状缺陷的形成。
