This study, in the area of non-destructive testing and measuring technology, shows that it is possible to
inspect and determine the mechanical properties and micro structure of a material using electro-magnetic
technique. The goal has been to on-line determine material properties like residual stress distributions,
variations in tensile strength and fatigue strength in a material. In the project the latest in materials inspection
using electro-magnetic methods combined with statistic modelling is used. The project has shown that these
new methods can non-destructively determine the mechanical properties of a material or a machine detail. It
is believed that this measuring technique has a clear place in industry.
