Detection technology and development of dynamic hardness tester

Hardness is the ability of a material to resist residual deformation and damage, and can also be interpreted as the ability of a material to resist elastic deformation, plastic deformation or damage. Hardness testing can reflect the elasticity, plasticity, strength and toughness of materials, as well as a comprehensive evaluation of a series of different physical properties and mechanical properties, so it is widely used in various production industries or fields.

There are many methods for hardness testing, including static hardness testing and dynamic hardness testing, as well as other types such as ultrasonic hardness tester (not discussed here), where static hardness refers to Rockwell hardness, Vickers hardness and Brinell hardness; Dynamic hardness testing refers to the hardness and Shore hardness, and the dynamic hardness test described herein refers specifically to the Leeb hardness tester.
