The measurement of residual stresses with particular reference to alloy steel forgings by a trepanning method and by Sachs method is discussed. The precautions necessary are investigated experimentally. The possibility of plastic yielding during the machining operations in the Sachs method is demonstrated and the effect of this on the residual stress distribution in water-quenched mild-steel cylinders is investigated.
The determination of residual stresses in an induction-hardened roll is given as an example of the use of some of the refinements described.
