An extensometer structure includes a first extension arm having a first mount configured to support a first specimen engaging member and a second extension arm having a second mount configured to support a second specimen engaging member. A connecting member extends between the first and second extension arms and pivotally connects to each of the first and second extension arms between each corresponding mount and a remote end of the extension arm. A rear coupling assembly connects remote ends of the extension arms together.

Extensometer structure

Specimen grip

Hydraulically actuated grips are constructed to permit loading of specimens from either side of the grips. The grips are particularly adapted for use with flat specimens, are easily actuated, and are symmetrically designed so that when actuated, the grips do not exert any substantial axial load on the specimen and a uniform clamping force is applied laterally across the specimen. In addition, the grips, which can be used for either tensile or compressive loading, do not exert any bending moment on the specimen during test loading.
