摘要： A method for estimating elastic properties of a subsurface material having a bedding plane includes disposing a single sample of the subsurface material in a core holder, the core holder having (i) a first acoustic transducer set having a first acoustic source and a first acoustic receiver and (ii) a second acoustic transducer set having a second acoustic source and a second acoustic receiver. The method also includes performing at least five acoustic wave velocity measurements on the single sample that include compressional acoustic wave velocities and shear wave acoustic velocities with a certain direction of shear acoustic wave polarization using the first set of acoustic transducers and the second set of acoustic transducers, estimating, with a controller, the elastic properties using the at least five acoustic wave velocity measurements, and providing an output signal having the elastic properties to an output signal receiving device.
