Abstract
Application of Sachs’ method to the measurement of residual stresses in hard cylinders is difficult. The authors succeeded in carrying out the measurement by using electric spark machining for boring and a resistance strain meter for strain measurement. In the present paper, they deal with the problems encountered in the practice of this method and with their solutions, bearing in mind the measurement of the residual stresses in water-quenched carbon tool steel cylinders; the results on these cylinders are illustrated.
