AN APPARATUS FOR AND A METHOD OF CHARACTERISING MECHANICAL PROPERTIES OF A SAMPLE

摘要

The present disclosure provides an apparatus for characterising mechanical properties of a sample. The apparatus comprises a structure for supporting the sample and applying a first pressure in a first direction to the sample and an actuator for modulating the first pressure. The apparatus also comprises a pressure applicator containing a liquid and arranged to apply a second pressure to the sample in a second direction that is transversal to the first direction. Further, the apparatus comprises a pore pressure applicator arranged to apply a flow of a fluid through a porous sample such that a pore pressure is applied to the porous sample. In addition, the apparatus comprises a sensor for sensing a change in the sample in response to a change in a pressure experienced by the sample.
