For many materials, the stress-strain curve looks like the curve shown in the figure below. As the stress is increased from zero, the strain increases linearly until it starts to deviate from linear at the yield strength.
1.4: Stress-Strain Curves - Engineering LibreTexts
Since it is often difficult to pinpoint the exact stress at which plastic deformation begins, the yield stress is often taken to be the stress needed to induce a specified amount of permanent strain, typically 0.2%.
Plasticity (physics) - Wikipedia
In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. In engineering, the transition from elastic behavior …

Stress-Strain Curves: Interpretation and Analysis
Learn to interpret and analyze stress-strain curves, understand material properties, elastic and plastic deformation, and yield strength for engineering applications.
The stress-strain curve for brittle materials are typically linear over their full range of strain, eventually terminating in fracture without appreciable plastic flow.
Curve A illustrates the stress– strain character for a brittle polymer, inasmuch as it fractures while deforming elastically. The behavior for a plastic material, curve B, is similar to that for many …
Plastic behavior can be studied by considering an idealized elasto-plastic material for which the stress-strain diagram consists of the two straight-line segments shown in Figure 16.4.
