Description: Stress-strain curves for brittle and ductile materials. Brittle materials fracture at low strains and absorb little energy. Conversely, ductile materials fail after significant plastic strain (deformation) and absorb more energy. Note that in this idealised example, the yield and ultimate tensile stresses are the same for both materials; brittle or ductile behaviour are not necessarily related to strength.
