Brittle

Brittle

Brittleness describes the property of a material that fractures when subjected to stress but has a little tendency to deform before rupture. Brittle materials are characterized by little deformation, poor capacity to resist impact and vibration of load, high compressive strength, and low tensile strength. Brittle materials include glass, ceramic, graphite, and some alloys with extremely low plasticity, in which cracks can initiate without plastic deformation and can soon evolve into brittle breakage. Metals which are brittle are basically alloy, pig iron, cast iron; steel with high carbon content is brittle. Explanation: An element is said to be brittle if it is hard but breaks easily with little force.

The ductile materials are Steel, Aluminum, copper etc. Brittle materials break without significant plastic deformation under tensile stress. Also called sudden failure. Brittle material absorbs little energy prior to rapture. The brittle material is glass, Plain concrete, cast iron, etc. Ductile substances can be easily hammered or stretched into thin wires without breakage. This physical property is explained as ductility. Brittle substances are liable to break easily. These substances are hard, and cannot be hammered or stretch like ductile substances; instead, they break.
