Repeatability of residual stress measurements

Residual stresses are of interest from an engineering perspective because they can have a significant influence on material performance. For example, fatigue initiation, fatigue crack growth rate, stress corrosion cracking, and fracture are all influenced by the presence of residual stress. Current design methods for aerospace structure typically assume that the material is residual stress-free.
