BRAINCAKEMore Stress-Strain Graphs
A ductile material can be drawn into wires or hammered into sheets(malleable). Copper and steel are ductile.
A strong material is one with a high ultimate tensile strength. This is the maximum stress a material can withstand when being stretched before breaking. Beyond this point, necking may occur.
