Definitions

Plastic Deformation
Material no longer returns to original length when force is removed.Occurs beyond elastic limit.Ultimate Tensile Stress
Beyond the UTS (breaking stress) the wire loses its strength.The wire extends, becomes narrower at its weakest pointwith a reduced cross-section area.

BrittleBreaks without any noticeable yield/plastic deformation.
DuctileCan be drawn into a wire.
