ABSTRACT:
A hydraulically actuated collet type grip with an elastic support structure to allow for the axial bending needed to compensate for diametral dimension changes in the specimen gage section to be accomodated within the grip rather than within the tubular specimen. The tabbed end of the tubular specimen is gripped in the annular region of the loud transfer section of the collet. Load transfer is achieved by normal pressure on the collet and the frictional interface between the collet and the bonded end tabs on the specimen.
