Knowledge of elastic and damping properties of materials is very relevant for the analysis and design of components, as they are relevant parameters in the performance of structural materials. The impulse excitation technique is a renowned dynamic technique for measuring dynamic elastic properties as Young´s modulus, shear modulus and Poisson’s ratio, as well as damping properties. This paper provides a review on the applicability of the impulse excitation technique in the analysis of elastic and damping properties of different types of materials.
