Residual stress measurement

Residual stress is defined as the stress that remains in a body that is not being sub- jected to external forces. Measure - ment of residual stress is important in predicting service life, analyzing distortion, and determining. Determination_of_Residual_Stresses_by_X-ra. X-ray Diffraction – Issue 2.
