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。

With the analysis of stress intensity factor near the crack tip of the cracked metallic panel,the influence of residual thermal stress on repairing cracked metallic panel with composite patch bonded is investigated.
