The toughness of a material can be defined as, ‘the ability of a material to absorb sudden shock without breaking or shattering.

A simple school workshop test is to hit a sample of material with a hammer, whilst it is secured in an engineers vice. If it survives the blow, without bending too far, it can be said to be tough. If it shatters, it can be said to be brittle.

 
 
 
 
 
The industrial device below measures toughness. The pendulum is allowed to ‘swing’ from a set starting position. The resulting ‘distortion’ to the sample material can be measured on the scale. This gives an indication of the materials toughness.
