摘要： An extensometer (10) is used for measuring axial and diametral strains in a material test specimen (12). The extensometer (10) comprises an assembly of extensometer sections (11, 13) positioned on diametrally opposite sides of the specimen (12) with specimen engaging points (22, 35, 67, 83) spaced axiallly along the specimen. The extensometer assembly (10) is arranged so that the two extensometer sections (11, 13) will average the axial strain measured by the two extensometer sections (11, 13). Also, if desired, the two extensometer sections (11, 13) may provide an indication of the average change in diameter of the specimen at the location of the upper contact points (67, 22) and at the location of the lower contact points (35, 83) of the extensometer sections (11, 13) on opposite sides of the specimen (12). The support system (15) between the extensometer sections (11, 13) provides for the necessary degrees of freedom to provide measuring only in the axis desired, and sufficient restraint in other axes to insure that accurate measurements are obtained.

摘要： A strain gage element system includes a spring flexure member (26) on which strain gages (37) of convention design are mounted, and a heat shrinkable waterproof tube (50) that is placed over the gage (37) and the support and shrunk into place. The spring flexure member (26) is formed so that it has a substantially constant peripheral length about the perimeter of any cross-sectional plane perpendicular to the longitudinal axis of the spring flexure member (26). The heat shrinkable tube (50) must be selected in size and shrinkage characteristics to tightly envelope and shrink against the gage (37) and spring flexure member (26) and seal the gage (37) completely to prevent moisture of any kind from getting into contact with the gage (37).

摘要： An extensometer (10) for measuring strain in a specimen (35) on which the extensometer (10) is mounted which has two arms (11, 12) joined together at first ends, and with specimen engaging knife edges (31, 32) at the second ends. The knife edges (31, 32) will engage a specimen (35) at spaced locations, so that when the specimen (35) is subjected to a load, the knife edges (31, 32) will separate, and the amount of separation will be an indication of the strain in the specimen. The distance between the knife edges is known as the 'gage length' (34, 78, 80, 100, 102, 122) and the extensometer provides a mounting (11B, 12B, 36, 84) for the knife edges (31, 32) in a plurality of positions so the gage length (34, 78, 80, 100, 102, 122) of the extensometer is changed as needed.

摘要： An extensometer assembly (10) accurately measures axial strain, torsional strain and various combinations of these strains in a specimen (12) on which the extensometer assembly (10) is mounted. The torsional strain measurement is made by measuring angular displacement about the longitudinal axis (20) of the specimen (12) with one extensometer (13) at the same time separately measuring the elongation of the specimen (12) with a separate extensometer (11) linked to the torsional measuring extensometer (13) by supports (15, 16, 17) having the necessary degrees of freedom so that readings from the respective extensometers (11, 13) are not subjected to excessive "cross talk", and at the same time torsional movement between the extensometers (11, 13) about an axis perpendicular to the longitudinal axis of the specimen is resisted.

摘要： A capacitive extensometer (60) has an extensometer frame formed of a pair of arms (61, 62) having first ends with specimen contacting members (73) and which are arms (61, 62) connected together about a hinge axis (72) at second remote ends. The specimen contacting members (73) engage the surfaces of a specimen (74) to be tested. A capacitive type sensing arrangement (100) is mounted on the arms, and is used with conventional circuitry for determining arm motion. The sensing members (106, 115) are located to insure adequate output, and can be located to the exterior of the periphery of the extensometer arm assembly. The ability to mount the capacitor sensor (100) appropriately, while obtaining a relatively large output signal enhances the operability the extensometer (60).

摘要： A high temperature extensometer system (10) carries specimen contact rods (50, 51) of substantial length which pass through openings in a furnace (12) to engage a specimen (11) in such furnace (12). The rods (50, 51) are supported at the exterior of the furnace (12) on a parallelogram linkage support frame (60) made to provide an output indicating specimen strain as the contact rods (50, 51) separate and also made with parallel beams (61, 62, 63, 64) which shift so the rods (50, 51) can move differentially in longitudinal axial direction. The rods (50, 51) shift axially when the specimen (11) and test loading grips (13, 16) shift in position, for example when the grips (13, 16) and specimen (11) are initially heated.

摘要： A capacitive extensometer (70) utilizes an extensometer frame having a pair of arms (71, 72) connected together about a hinge axis (96) at first remote ends, and having second ends which include specimen contacting members (80) for engaging the surfaces of a specimen to be tested. A capacitive type sensing arrangement (83) is mounted on the arms, and is used with conventional circuitry for determining arm motion with respect to each other. The sensor is made so that it can be adjusted, and also can compensate for nonlinearities by utilizing differently shaped elements (90). The ability to mount and protect the capacitor sensor appropriately, while obtaining a relatively large output signal enhances the operability of the extensometer.

摘要： A support system (30, 31, 35, 40, 50, 60) provides a stable reference frame to support an extensometer assembly (25) that measures both axial and torsional strains in a specimen (13). The reference frame (30, 31, 35, 40, 50, 60) is made so that it will retain an optimal relationship between the specimen (13) and the test machine (10) which is used for loading the specimen. The reference frame is made so that it will not substantially change position in relationship to the specimen (13) during the specimen loading, or cross talk from one measurement axis to the other, while accomodating load frame deflections during the application of axial and torsional loads on the specimen (13).
