Abstract
Summary
A new experimental system has been designed and commissioned to measure dynamic elastic properties at seismic frequencies under deviatoric stress. A specialized servo-hydraulic load frame with a pair of laser displacement sensor is applied in this research. Calibration has been completed using aluminum, which has well-known properties. The results show the stability and accuracy from 0.001 Hz to 1Hz and the system performance has been tested using 3D printed sandstone specimens (using sand as the print medium) that provide an unparalleled opportunity to remove inter-specimen variability in the testing. The results show the frequency dependence of elastic moduli.
