A new concept, the equivalent inherent strain g o (eq), is proposed for measuring axisymmetric residual stresses, based on the inherent strain theory. g o (eq) is a parameter obtained by incorporating the radial inherent strain component into the tangential inherent strain component in computing the axially uniform axisymmetric residual stresses. The application of this concept can avoid the restriction of radial inherent strain component estimation and hence leads to a more simple and accurate method for measuring axisymmetric residual stresses. Experimental measurement and numerical simulation were carried out to demonstrate that this method has both the simplicity of the Sachs method and the high accuracy of the inherent strain method.
