Analysis and Comparison of Measured Static and Dynamic Moduli of a Dolostone Specimen
Laboratory estimation of elastic moduli of rocks is required in many engineering applications including infrastructure construction, slope stability analysis, mining, and energy technologies. Two mechanical tests, cyclic and multi stage elastic test along with concurrent measurement of P-wave and cross-polarized S-waves velocities were performed on a dolostone specimen obtained from a road cut in Shelburne, Vermont. While deformational response of the specimen was used to determine its static moduli, P- and S-waves velocities were used to determine the dynamic moduli (i.e. bulk modulus, Young’s modulus, and Poisson’s ratio). The rate of increment of static bulk modulus during hydrostatic stage was observed to be higher than that of the dynamic bulk modulus. Dynamic Young’s moduli were observed to be higher than the static moduli, whereas the dynamic Poisson’s ratio were smaller than the corresponding static ones. Moreover, the static Young’s moduli, during unloading cycle, were observed to be higher than the corresponding loading cycle. The results obtained in this study are in agreement with the previously published results.
