What do you mean by brittleness?

Answer 1

Aptness to break; fragility.

Answer 2

Brittleness refers to the tendency of a material to break or shatter without significant deformation when subjected to stress or impact. Materials with low toughness are typically considered brittle. Examples include glass and some ceramics.

Answer 3

A material that is easily broken - usually shattered is a brittle material. It has poor toughness and poor resistance to fracture. Sometimes a material can be very hard and yet brittle. Glass is one such material. It is very hard but has very poor resistance to fracture. Lead is extremely soft but is not a brittle material.

Answer 4

the brittleness o a materials is the property of breaking or shattering without much permanent distortion.many materials shatter before deformation take.such materials are brittle e.g. glass,cast iron.therefore. a non ductile material is a brittle material

Answer 5

Brittle

A material is brittle if it is subject to fracture when put under stress or strain. This fracture absorbs relatively little energy, even in materials of highstrength.

When used in materials science, it is generally applied to materials that fail in tension rather than shear, or when there is no evidence of plastic deformation before failure.

When a material has reached the limit of its strength, it usually has the option of either deformation or fracture. A naturally malleable metal can be made stronger by impeding the mechanisms of plastic deformation (reducing grain size, dispersion strengthening , work hardening, etc.), but if this is taken to an extreme, fracture becomes the more likely outcome, and the material can become brittle. Improving material toughness is therefore a balancing act.

This principle generalizes to other classes of material. Naturally brittle materials, such as ceramics (most famously glass), are difficult to toughen effectively. Most such techniques involve one of two mechanisms: to deflect the tip of a propagating crack, for instance by introducing natrual weaknesses of limited extent, or to create carefully controlled residual stresses so that cracks from certain predictable sources will be forced closed, as in the case of toughened glass and pre-stressed concrete. Both mechanisms tend to soften the material somewhat, although most ceramics are quitehard to begin with. The least-brittle structural ceramics are silicon carbide (mainly by virtue of its high strength) and transformation-toughened zirconia.

Answer 6

Brittleness is the opposite of flexibility. If you bend something, it can either change its shape and become bent but remain intact, or it can break at the location where you are bending it. Brittleness is the degree of susceptibility to breaking as a result of that kind of stress, which would cause a more flexible material to bend.

Answer 7

Brittle is basically something that is Hard but is also liable to break or shatter easily.

Answer 8

The English word 'brittleness' means hard, yet easily broken

.

Brittleness is lack of flexibility.

Answer 9

The property in which a nonmetal break down into pieces on hammering is called brittleness . Nonmetals like Hydrogen , Oxygen , Nitrogen are not brittle as they appear in gaseous form.

Answer 10

Glasses, crystal

and any solid that breaks easily.
