Abstract:
This article considers a series of three experiments on the elastoplastic deformation of the V95 alloy, which is sensitive to the type of stress state. Experimental studies were carried out on a CL-EVM (complex loading) test machine on thin-walled tubular specimens during their deformation along two-link strain trajectories with 90 degree break angles. Experimental studies were carried out in the deviatoric plane $\text{Ý}_{1} -\text{Ý}_{3} $ with simultaneous combined action of axial force and torque on tubular specimens (P – M experiments). The scalar and vector properties of the V95 aluminum alloy are studied. It is found that for the implemented complex strain trajectories in the form of two-link polygonal lines for the V95 material, the isotropy postulate is not fulfilled accurately enough in terms of scalar and vector properties.
Key words:
plasticity, complex loading, isotropy postulate, experimental data, two-link broken line, strain trajectory, vector and scalar properties of material, V95 aluminum alloy.
