Studying magnetic stray field at the surface of elastostrained extensive object

Resumo

Application of metal magnetic memory effect to revealing stress-concentration zones (SCZ) that occur in a specimen due to cyclic loads within the elastic deformation domain is considered. Experimental data are provided on the search for a correlational dependence between the magnetic stray field of a hot-rolled no. 6 channel bar and the stresses in the domains of elastic and plastic deformation.
