Abstract
An extensometer structure for an extensometer comprises a flexure assembly, a first extension arm and a second extension arm. The flexure assembly includes a first flexure defining a first plane and a second flexure defining a second plane. The second flexure is coupled to the first flexure so that the first and second planes intersect. The first extension arm is joined to the first flexure and has a first tip engageable with a test specimen wherein a line of force from the first tip extends parallel to the first plane. The second extension arm is joined to the second flexure and has a second tip engageable with the test specimen wherein a line of force from the second tip extends parallel to the second plane.
