On Question of Metals’ Plasticity

Abstract:

Straightforward and reverse descriptions are used to describe the metal’s plasticity zone. For the straightforward descriptions of the hardening zone, the “reference” point is the relative deformation ε_y corresponding to the yield strength σ_y. The deviation of the relative deformations in the metal hardening zone is measured relative to ε_y, and the deviation of the normal stresses is measured relative to σ_y. For the reverse descriptions of the metal hardening zone, the “reference” point is the relative deformation ε_u corresponding to the ultimate strength σ_u. The deviation of the relative deformations in the metal hardening zone is measured relative to ε_u, and the deviation of the normal stresses is measured relative to σ_u.
