     this article presents the experimental results of damping loss factor and young’s modulus obtained for stiff and flexible materials through the use of four different methodologies: the central impedance method, the modified oberst method, the seismic response method, and the simply supported beam method. the first three methods are based on the astm standard but using different experimental setting and different frequency response functions. the fourth method corresponds to a non-resonant technique used in the characterization of materials at very low frequencies. in this work, the results of damping loss factor and young’s modulus obtained through these four methods are compared, the variability of results is studied and the sensitivity of each technique when facing controlled temperature variations is verified.
