WebA material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation.Brittle materials absorb relatively little energy prior to fracture, even those of high strength.Breaking is often accompanied by a sharp snapping sound. [citation needed]When used in materials science, it is generally applied to … WebA ductile material is a material, where the strength is small, and the plastic region is great. The material will bear more strain (deformation) before fracture. A brittle material is a material where the plastic region is small and the strength of the material is high. The tensile test supplies three descriptive facts about a material. WebIt starts with initiation of a crack, followed by crack propagation.
