Popis:	Springback prediction has become a major focus in sheet metal forming. Validation of finite element codes for springback prediction require accurate property data and a more complete understanding of the residual stresses that are involved. To provide experimental data for these calculations, neutron and X‐ray diffraction measurements were carried out to determine the through‐thickness distribution of residual stresses in test specimens of several steels and AA6022‐T4 alloy. The techniques are able to provide true spatial resolutions of approximately 0.1 mm for strain measurements at wall thicknesses of ≈1 mm.
