Correction of a neutron diffraction peak shift due to a partial immersion of a gauge volume in an unstressed sample

► Near-surface measurement of residual stress with neutron diffraction. ► Effect of variation of peak diffraction positions if the gauge volume is partially immersed in a sample. ► Correction of the peak position on the pseudostrain effect. ► Reductive analytical approach to account for the pseudostrain effect in a thin-walled sample was developed. ► Correction of the pseudostrain effects into experimental data of Spooner and Wang [2] was perfect.
