WebOct 24, 2024 · (b) Stress strain curves for brittle materials : Materials which show very small elongation before they fracture are called brittle materials. The shape of curve for a high carbon steel is shown in Fig. (b) and is typical of many brittle materials such as G.I, concrete and high strength light alloys. WebToughness is related to the area under the stress–strain curve. In order to be tough, a material must be both strong and ductile. For example, brittle materials (like ceramics) that are strong but with limited ductility are not tough; conversely, very ductile materials with low strengths are also not tough.
