Abstract
Knowing the mechanical characteristics of materials is crucial for properly interpreting the results attained from experiments. In this paper, we present a method to experimentally determine the Young modulus of various materials by employing multi-modal analysis. The method, which implies finding the structures’ natural frequencies, is based on the resonance test. If the natural frequencies are known, the dynamic Young’s modulus can be extracted from the relation that expresses these frequencies in respect to the stiffness. An advanced signal processing algorithm is proposed for precise frequency evaluation. The algorithm constitutes the core of the method; herein we demonstrate how it is involved to extract the frequencies of several bending vibration modes. Tests were made by involving non-contact and impulsive excitation, respectively, the fist one providing best repeatability.
