文摘

We have shown how crucial it is to determine the residual stresses (RS) at the stages of the product life cycle by means of the non-destructive testing (NDT) magnetic methods and to create computational algorithms and models. The experimental results of the RS in rod-shaped specimens after the 3-point-bending by magnetic-noise analysis and coercive force measurement are proved as being topical. The interrelations between the value of the change undergone by magnetic characteristics that are measured by the NDT magnetic methods and the value of the axial RS resulted from modeling by finite element method are revealed.Keywordsnon-destructive testingresidual stresseslife cycledurabilitytechnological inheritance
