The localized compressive stress induced at the area of contact between the two components, having no relative motion between them, is called crushing stress. Examples of components subjected to crushing stress: Pin and eye, threads of nut and bolt, key and shaft, etc.

The Aggregate Crushing Value (ACV) Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.
The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load
Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load.

Manufactured aggregate is produced by crushing sound parent rock at stone crushing plants. Crushed aircooled blastfurnace slag is also used as fine or coarse aggregate. As a result of the crushing operation, manufactured aggregates often have a rough surface texture, are more angular in nature, tend to be cubical or elongated in shape, and more uniform in size.
