SHEAR TEST (SINGLE SHEAR AND DOUBLE SHEAR)

BUILDING MATERIALS TESTING LABORATORY
Theory:
Shear stress is caused by forces which act parallel to an area of cross section and tend to produce sliding of one portion past another portion. If there is only one cross section which resists the failure, the material is said to be in single shear (figure 5.1) and the average ultimate shear strength will be equal to the failure load divided by the area of cross section. If two areas resist the failure then the material is said to be in double shear (figure 5.2) and the average ultimate shear strength will be equal to the failure load divided by twice the area of cross section.

A special shear attachment called Shear Shackle is used to keep the specimen. The specimen can be placed either one end supported or two ends supported in the shackle. One end supported specimens fail under single shear and both ends supported specimen fail under double shear.
