The pit then grows through the compressivelayer, and the change in residual stress state and the pit geometry initiate stress corrosion cracking.
随后斑点穿过压缩层继续扩展,剩余应力发生改变,斑点最终导致应力腐蚀裂纹。

These larger ions take up more room and are pressed together when the glass cools, producing a layer of compressive stress on the surface of the glass.
Restoration of the shot-peened layer during overhaul is important to ensure that the shot-peen compressive residual stresses are maintained or restored.
