On determining the elastic modulus of a cylindrical sample subjected to flexural excitation in a resonant column apparatus
On determining the elastic modulus of a cylindrical sample subjected to flexural excitation in a resonant column apparatus
For resonant column tests conducted in the flexure mode of excitation, a new methodology has been proposed to find the elastic modulus and associated axial strain of a cylindrical sample. The proposed method is an improvement over the existing one, and it does not require the assumption of either the mode shape or zero bending moment condition at the top of the sample. A stepwise procedure is given to perform the necessary calculations. From a number of resonant column experiments on aluminum bars and dry sand samples, it has been observed that the present method as compared with the one available in literature provides approximately (i) 5.9%–7.3% higher values of the elastic modulus and (ii) 6.5%–7.3% higher values of the associated axial strains.

Abstract
For resonant column tests conducted in the flexure mode of excitation, a new methodology has been proposed to find the elastic modulus and associated axial strain of a cylindrical sample. The proposed method is an improvement over the existing one, and it does not require the assumption of either the mode shape or zero bending moment condition at the top of the sample. A stepwise procedure is given to perform the necessary calculations. From a number of resonant column experiments on aluminum bars and dry sand samples, it has been observed that the present method as compared with the one available in literature provides approximately (i) 5.9%–7.3% higher values of the elastic modulus and (ii) 6.5%–7.3% higher values of the associated axial strains.
