ABSTRACT:
An end-cap-to-piston coupling, with or without an integral load cell has been developed for triaxial test apparatus. One triaxial test apparatus shown has a housing, sample mounting apparatus in the housing, a load piston opening through the housing through which projects a load piston, and a load transfer coupling, with or without an integral load cell, interposed between the end cap and the load piston. In one aspect the coupling has a coupling body and a channel on one end into which the load piston is inserted to contact a shoulder of the coupling body. Another end of the coupling has a channel which receives a top end cap of a sample mounting arrangement. This channel may be sized and configured to receive a load transfer ball interposed between the coupling and the end cap or between the coupling and the piston. In one aspect a series of interchangeable top and bottom members are provided, each with a different diameter recess, to accommodate load pistons and sample end caps of different diameters.
