Abstract: In this paper influence of uniaxial stress loading on local changes
of magnetic properties in a non-oriented silicon steel was examined. The
measurements were carried out for different direction of loading force in
respect to the rolling direction of the steel. Impact of the relationship
between the rolling and the loading direction on evaluation of magnetic
properties changes caused by stress was investigated using samples cut out at
three different angles from the steel sheet. During the experiments two types
of transducers with two and three sensitivity axes operating under rotating AC
and static DC field were utilized. First, the observation of local changes of
parameters related to a vector magnetic flux was carried out. Then algorithms
of measured signals parameterization were utilized and evaluation of the stress
distribution in tested samples was proceeded. Finally, the statistical analysis
of computed signals parameters was applied and the correlation with
stress-strain curve was assessed.
