摘要： A test specimen holder for holding a test specimen in a material testing machine includes a base member having a piston chamber, a valve chamber fluidly coupled to the piston chamber, a port fluidly coupled to the valve chamber and an end couplable to a material testing machine. A piston is movable relative to the piston chamber. A pair of first and second jaw assemblies are supported by the base members so as to be opposite each other. The jaw assemblies are operably coupled to the piston. A valve is disposed in the valve chamber and a valve stem is coupled to the valve. The valve stem is supported by the base member and is twistable to operate the valve. A user operable knob is coupled to the valve stem.

摘要： A test specimen holder for holding a test specimen in a material testing machine that applies force loads to the test specimen includes a base member having a first end coupleable to the material testing machine and a second end remote from the first end. A longitudinal axis extends from the first end to the second end. A body member extends from the second end to the first end and includes an aperture disposed on the longitudinal axis for receiving the test specimen. A displacement device displaces the body member relative to the base member substantially parallel to the longitudinal axis.
