Abstract

A new method of X-ray measurements of triaxial residual stresses was proposed for hexagonal polycrystals with the [001] fiber texture. The relation between the strain and sin2ψ is linear for the cases of the fiber axis perpendicular or parallel to the specimen surface, provided that there is no shear stress acting on the specimen surface. The in-plane stresses, σ11, σ22, and σ12, and the normal stress perpendicular to the specimen surface, σ33, are determined from the slope and the intercept of the linear regression line for the relation between the X-ray strain and sin2ψ obtained for three different directions.
