Measurement of elastic constants

Measurement of elastic constants

Elastic constants are of fundamental importance for e.g. industrial applications and the understanding of the functioning of biological materials. These constants can be measured nondestructively with either the Resonant Beam Technique (RBT) or Resonant Ultrasound Spectroscopy (RUS) both at room temperature and temperatures up to 700°C (RUS) and 1900°C (RBT) in vacuum and inert gas.

See one of the following publications if you want to know more about the two methods:
