| Abstract |
The article presents the results of an experimental study of complex elastoplastic deformation of L63 brass along two-link broken strain trajectories in the deviatoric strain space. The description of the experimental program, presentation and discussion of its results are carried out in the vector
representation of stresses and strains using the terminology and approaches of A.A. Ilyushin’s theory
of elastoplastic processes. The experiments were carried out in the mechanical testing laboratory of
Tver State Technical University using the automated testing machine SN-EVM under combined loading of thin-walled tubular specimens with axial force and torque (P+M experiments). The loading
process was assumed to be isothermal, and the strains were considered small. The material of the specimens was sufficiently isotropic initially, as confirmed by experiments under simple loading. The test
programs were implemented in the deviatoric space of strains Ý1−Ý3
(rigid or kinematic loading).
Two-link broken trajectories with the first link length of
Ý1=3% and fracture angles of 90°, 135°, and 180° are investigated. Experimental diagrams characterizing the scalar and vector properties of the L63
brass material are presented. Approximations of deformation diagrams under simple and complex loading are proposed. The research results can be used in constructing mathematical models of plasticity theory. |
