Popis: Localized inhomogeneous plastic deformation phenomenon was experimentally investigated in a structural steel by using the magnetic Barkhausen noise measurements. ANSI 1050 steel plates, throughout oriented in the rolling transversal direction, were selected additionally inducing different strains. Scanning of the magnetic Barkhausen energy (MBN energy ) shows the formation of Luders bands as well as the displacements in the material deformation zone. The MBN energy angular dependency on the applied stress and on the anisotropy coefficient were determined as well as the presence of Luders bands in samples oriented according to the rolling direction.
