Estimation of the elastic tensile and compressive modulus through measuring the displacement filed in Brazilian disc test

摘要

In this study, a completely analytical experimental theory is developed to determine the elas-tic tensile modulus E1 and the elastic compressive modulus Ec simultaneously through the deformation and displacement measurement in the Brazilian disc loaded by a pair of radial concentrated forces. Two groups of experimental data are used to validate the proposed test method. The results indicate that the proposed method is feasible, and is convenient to determine the E, and Ec through simple indirect tension test (Brazilian disc test).
