Abstract
A new and quick approach is proposed to evaluate Poisson's ratio of materials with only the measured longitudinal and cross-sectional resonance frequencies from the impact-echo test on a solid circular rod of known dimension. Both the longitudinal and guided wave propagation theories are used to derive the required equations through regression analysis. Procedure to verify the adequate length of solid rod specimen to obtain a valid Poisson's ratio is described. Experimental data of four materials, concrete, steel, stainless steel and brass, illustrated with the proposed approach show satisfactory results.
