An Adjustable Combined Loading V-Notched Rail Shear test fixture has been developed.\u00a0 This fixture is shown in comparison to the standard V-Notched Rail Shear Test Fixture in Fig 6. Note that the depth of the cavity in which the specimen is gripped has been increased from 1 in. to 2 in. in the Combined Loading Shear test fixture (left) to provide greater surface area and edge distance for specimen loading. Whereas the standard V-Notched Rail Shear specimen is 3 in. x 2.2 in. as shown above in Fig. 4, the Combined Loading Shear specimen is 5 in. x 2.2 in. However, the size and shape of the central notched test section of the specimen is the same for the two test configurations.<\/p>\n\t\t\t\t\"CLSSideBySide2\"\n\t

The adjustable Combined Loading Shear test fixture is shown partially disassembled in Fig. 7.\u00a0 A flat plate contacts the edge of the specimen, being held against the specimen by a screw.\u00a0 This screw can be used to adjust for the width of the specimen, or to actually apply a preload to the specimen edges.<\/p>\n\t\t\t\t\"IMG_3522\"\n\t
