Brittle Fracture - an overview | ScienceDirect Topics

Brittle Fracture. Brittle fracture is an unstable failure process that occurs in fibre–polymer composite materials, metals with high strength and low ductility, and in some metal types at low temperature (i.e. below the ductile/brittle transition temperature).

The strength of brittle construction materials, like masonry and concrete, is highly sensitive to the quality of construction materials, workmanship, supervision, and construction methods. Similarly, special care is needed in construction to ensure that the elements meant to be ductile are indeed provided with features that give adequate ductility.

Brittleness - Wikipedia

A material is brittle if, when subjected to stress, it breaks without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a snapping sound.

Fig.2: Ductile Material vs. Brittle Material. Ductile Chain Design concept in building as per capacity design. When a brittle chain alone is pulled on either side, it would break suddenly.

Ductile and Brittle Materials | Difference Between Ductile ...

Ductile materials exhibit large strains and yielding before they fail. Steel and aluminum usually fall in the class of Ductile Materials; Brittle Materials: Brittle materials fracture at much lower strains. Brittle materials often have relatively large Young's moduli and ultimate stresses. Brittle materials fail suddenly and without much warning.
