Webhysteresis is reduced until the stress-strain curves overlay each other (within experimental error). This line, shown as the dotted line in the figure here, is the stress-strain curve at thermodynamic equilibrium. The area under the stress-strain curve is the work applied to stretch the material and the work recovered during relaxation. WebMar 5, 2024 · The experiment on loading/unloading tell us that the total strain ϵ total can be considered as the sum of the plastic strain ϵ plastic and elastic strain ϵ elastic. Thus. (11.1.1) ϵ total = ϵ plastic + ϵ elastic. The elastic component is not constant but depends on the current stress. (11.1.2) ϵ elastic = σ E.
