摘要
An apparatus (10) and method for performing nonlinear elasticity measurements using the dynamic acousto-elasticity technique (DAET) at simulated subsurface conditions in the laboratory, are described. The current state-of-the-art for measuring non-linear elasticity parameters using DAET is limited to ambient pressure conditions on the bench-top. The present invention permits non-linear parameter measurements at controlled sample internal fluid pore pressures (52) and external confining stress (44), (50) conditions.
