ABSTRACT:
Methods and apparatuses are disclosed for determining a three factor envelope for the material of a preserved core sample. The three factors are ultrasonic velocity through the material, mean effective stress and an elastoplastic property of the material. Values are obtained, in one aspect of the invention, by applying a confining pressure to the material; measuring the material's pore pressure and the ultrasonic velocity therethrough; calculating the material's mean effective stress for that confining pressure; and then loading the sample to near shear failure to measure the value of the elastoplastic property. At different confining pressures the measurements are repeated on the same sample to obtain values for the mean effective stress and elastoplastic property at each level. The envelope is determined by graphically representing the data obtained.
