The engineering properties of materials and structural components, notably fatigue life, distortion, dimensional
stability, corrosion resistance, and brittle fracture can be considerably influenced by residual stresses [1]. Such
effects usually bring to considerable expenditure in repairs and restoration of parts, equipment, and structures.
Accordingly, residual stresses analysis is a compulsory stage in the design of parts and structural elements and in the
estimation of their reliability under real service conditions [2].
Residual stresses occur in many manufactured structures and components. Different methods have been
developed to measure residual stress for different types of components in order to obtain reliable assessment. The
different residual stresses measurement methods are classified to destructive, semi destructive and non-destructive
techniques depends on their application and the availabilities of those techniques [3].
