Mechanical properties of material:
There are mainly two types of materials. First one is metal and other one is non metals. Metals are classified into two types : Ferrous metals and Non-ferrous metals. Ferrous metals mainly consist iron with comparatively small addition of other materials. It includes iron and its alloy such as cast iron, steel, HSS etc. Ferrous metals are widely used in mechanical industries for its various advantages.
Nonferrous metals contain little or no iron. It includes aluminum, magnesium, copper, zinc etc.
Most Mechanical Properties are associated with metals these are-
The ability of material to withstand load without failure is known as strength. If a material can bear more load, it means it has more strength. Strength of any material mainly depends on type of loading and deformation before fracture. According to loading types, strength can be classified into three types.
- Tensile strength:
- Compressive strength:
- Shear strength:
According to the deformation before fracture, strength can be classified into three types.
- Elastic strength:
- Yield strength:
- Ultimate strength:
If a material has same properties throughout its geometry, known as homogeneous material and the property is known as homogeneity. It is an ideal situation but practically no material is homogeneous.
