Spall
Sign in to savethumb|Very high-speed photography of a small projectile striking a thin [[aluminium plate at 7,000 m/s. The impact causes the projectile to disintegrate, and generates a large number of small fragments from the aluminium (spallation). This can occur without penetration of the plate.]]

Spall are fragments of a material that are broken off a larger solid body. It can be produced by a variety of mechanisms, including as a result of projectile impact, corrosion, weathering, cavitation, or excessive rolling pressure (as in a ball bearing). Spalling and spallation both describe the process of surface failure in which spall is shed.
