vector and scalar material properties, complex loading, experimental data, plasticity, trajectory deformation.

The article presents the results of an experimental study of deformation of a thinwalled tubular sample along a smooth curvilinear trajectory of deformation of different curvature, in which each section of the trajectory changes the value of curvature and moves it center. The experiments were carried out on an automated calculation and experimental complex SN-EVM in the deviatoric space deformations A.A. Ilyushin (hard loading) with simultaneous combined action on a thin-walled tubular tensile-compression sample and twists. Scalar and vector material properties were subject to research brass L63. It was revealed that the resulting diagrams that characterize scalar and vector material properties are oscillatory.
