Ultrasonic Characterization of Plastic Material 1999-01-0982
The industrial current design approach use more and more calculation tools to design technical parts. The more the properties of material are well known, the more the calculation is efficient and reliable. One of the way to recover real properties of a material is to measure them with an ultrasonic technique. This method is based on the fact that ultrasonic wave velocity depends on the material in which it goes through.
Ultrasonic technique appears then like a reliable device to study the properties of a material directly on an injected part without destroying it, and can be used in laboratory to characterize plastic or metallic materials.
