Engineering materials are divided inwards the next divisions -
1. Metal in addition to Metal Alloys . Example : Iron, Copper, Nickel etc.
2. Non- Metals . Example : Ceramics. rubber, drinking glass etc.

Important Mechanical Properties of Materials are Described Below :
b. Stiffness: This is measured yesteryear the modulus of elasticity. It is the mightiness of the fabric to resist deformation when stress is applied.
c. Elasticity: Elasticity is the mightiness of the fabric to find its master copy shape when the external forcefulness is removed. Steel's elasticity is greater than rubber.
d. Plasticity: This holding is the mightiness of the fabric to deform permanently. It helps to shape the fabric to brand into sparse plates or molds.
e. Ductility: Ductility is the holding of the fabric which makes it enable to larn sparse wire amongst the application of tensile forcefulness (equally intense pull). The mechanical properties of mild steel exhibit that it is rattling ductile.
f. Brittleness: Brittleness refers to the holding of the fabric due to which a fabric breaks amongst association of rattling petty distortion. Brittle materials are glass, ceramic, cast iron.
g. Malleability: It helps the fabric to live converted to sparse sheets or plates. It is truly a exceptional example of ductility. Malleable materials are prone to plastic deformation. They take non live strong. Lead, soft steel, copper etc are rattling much malleable which are used inwards the applied scientific discipline process.
h. Toughness: It is the mightiness of the fabric to forestall fracture when high touching on charge in addition to shocks are applied. Toughness is reduced when the fabric is heated.
i. Resilience: This holding is besides needed for resisting shocks in addition to impacts. Resilience refers to the issue energy absorbed inside the elastic boundary per unit of measurement volume.
j. Creep: This holding of the fabric states the phenomenon of permanent in addition to dull deformation of the fabric when subjected to constant stress at high temperatures. IC engines, boilers etc. are designed keeping this term inwards head.
k. Fatigue: when fabric is subjected to repeated loads, it fails earlier reaching the yield point. This type of failure is called fatigue. At origin cracks developed inwards the auto parts inwards microscopic score in addition to amongst fourth dimension the probability of failure increases.
l. Hardness: Hardness has dissimilar meanings. Resistance to wear, deformation in addition to scratches are expressed yesteryear hardness.
Mechanical properties of materials differ inwards metals in addition to non metals. Metallurgical in addition to Mechanical Engineers should bring skillful cognition most fabric properties.
