perform different indentation hardness tests on one machine

摘要

Testing is routinely carried out to provide insights into a material's mechanical properties and ascertain their suitability for the intended applications. Tests can include tensile and compression testing, impact resistance, fracture toughness, fatigue and hardness. These techniques involve the application of a load under dynamic or static conditions, with resultant behaviour noted and used to evaluate material property behaviour. Hardness or indentation testing evaluates how well materials resist deformation when a force is applied. It is an empirical test that has excellent correlation to direct measurement of mechanical properties such as ultimate tensile strength.
