Abstract The local surface crack has already been the main reason that has great negative influence on the fatigue life
and the resistance of foreign object damage of important equipment, such as the blades of aviation engine.
Laser shock peening (LSP) is a very effective technology for metallic surface treatment, which has been
widely used to overcome the negative influence of local surface crack. However, when LSP is applied to a
thin specimen, an undesirable result spall fracture, which is close to the free surface inside the specimen,
may occur.
The spall fracture phenomenon generated in LSP… More >
