Choice of Stress-Strained Condition Indexes for Construction of Plasticity Diagrams Via Computer Simulation
The paper covers determination of optimum indexes of cumulative deformation and stress condition. The indexes enables construction of a common plasticity diagram for experiments with a variety of types of stress condition. Various indexes of cumulative deformation are discussed and relative errors of the constructed plasticity diagrams for two types of the experiments were determined. The study is based on the results of replication of the tension and torsion experiments in a high-pressure chamber via QForm computer simulation.
