Method and apparatus for tensile testing of metal foil

摘要

Accurate, reproducible results in the tensile testing of thin metal foils are obtained by a method which comprises before placing the test specimen in a tensile testing machine, working the side edges of the test specimen until the edges are parallel and flaw-free, aligning the work specimen between spaced grip end members, securing end portions of the aligned test specimen to the grip end members, each of said grip end members containing female member means in face-to-face relationship to each other. The female member means are located on either side of and perpendicular to the plane of the test specimen and couple with corresponding male member means secured to the jaws of the tensile testing machine.
