ABSTRACT:
A core sample test apparatus applies pressure to the core sample and measures responsive longitudinal deformation with two sensors and lateral deformation with two orthogonal pairs of diametrically disposed sensors. The apparatus holds the core sample under test in a sleeve to which no or insignificant end torsional forces are applied during installation due to rotationally blocked washers used adjacent the ends of the sleeve. Concurrent acoustic testing can also be applied.
