Characterization
Aurock is equiped with a Resonant Frequency & Damping Analyser (RFDA). The RFDA test rig is used to do impulse excitation measurements from room temperature up to 1050°C under air. The RFDA measures resonant frequency and internal friction or damping of samples with all kinds of materials and calculates the Young's modulus, Shear modulus, Poisson ratio.
