A schematic diagram for the stress-strain curve of low carbon steel at room temperature is shown in figure 1. There are several stages showing different behaviors, which suggests different mechanical properties. To clarify, materials can miss one or more stages shown in figure 1, or have totally different stages. Typical graphical results for the complete stress-strain curves are shown in Fig. 5. Note the very large differences in the stress-strain characteristic, range from a very mild but ductile A36 steel to a very strong but non-ductile C1018. Note that both are conventionally called steel, but their performance is markedly different. The stress-strain curve is a graph that shows the change in stress as strain increases. It is a widely used reference graph for metals in material science and manufacturing. There are various sections on the stress and strain curve that describe different behaviour of a ductile material depending on the amount of stress induced.
