Bookmark and Share The impulse excitation technique measures the resonant frequency of a specimen after a small mechanical impact. Together with the geometry and mass of the specimen this provides enough information to determine elastic properties and damping. IMCE has developed a unique apparatus that can measure elastic properties continuously in high temperatures up to 1750C and in different atmospheres (air, vacuum, inert and reducing).  
The specifics of the technique and our equipments will be explained. A demonstration of our room temperature system (RFDA system 23) will be given.
Bio: Mr. Bollen is the co-founder of IMCE and a co-developer of the Resonant Frequency and Damping Analyser (RFDA) using the impulse excitation technique (IET) and its industrial applications. He has more than ten years experience in the field of material characterization, especially in the use of IET.
