Toughness | Definition | Measuring Tests [Brief Explanation]

What is Toughness? Toughness is the ability of a material to absorb energy before ultimate failure. Material which can absorb more energy before failure is considered more tough than another material which can absorb less energy. Unit of toughness is Joules per cubic meter. Tests for measuring toughness There are mainly two tests which are… Read More »

Hardness | Definition | Measuring Tests [Brief Explanation]

What is hardness? Hardness is the property of a material to resist surface indentation (and scratches). Some materials are harder than other materials. For example, metals are harder than plastics, wood etc. Difference between hardness and toughness Hardness is a property which is related to the surface of a material while toughness is a property… Read More »
