Abstract
Device for carrying out tests on materials such as rock samples for example, on which triaxial stresses are exerted. The device comprises an extended body with a central cavity where a first part (6) of a sonic sonde, a sole piece (9) carrying a cubic sample (12) for example, jacks (13) which are introduced along the lateral faces of the sample by connecting them with channels (25) supplying fluid under pressure are successively placed. A centering piece (27) containing a box (26) for another part (28) of the sonic sonde and elements (31, 32) forming a cover are placed above. A piston (35) allows to apply stresses to the sample by means of the box (26). Lateral sensors (22) pick up the displacements of the sample. Application to the examination of rocks taken from a subterranean formation for example.
