<p>An extensometer structure (11, 153, 201) for an extensometer comprises a flexure assembly (16, 156, 206), a first extension arm (12, 152, 202) and a second extension arm (14, 154, 204). The flexure assembly (16, 156, 206) includes a first flexure (18, 158, 208) defining a first plane (20, 160, 210) and a second flexure (22, 162, 212) defining a second plane (24, 164, 214). The second flexure (22, 162, 212) is coupled to the first flexure (18, 158, 208) so that the first (20, 160, 210) and second (24, 164, 214) planes intersect. The first extension arm (12, 152, 202) is joined to the first flexure (18, 158, 208) and has a first tip engageable with a test specimen (28) wherein a line of force from the first tip extends parallel to the first plane (20, 160, 210). The second extension arm (14, 154, 204) is joined to the second flexure (22, 162, 212) and has a second tip engageable with the test specimen (28) wherein a line of force from the second tip extends parallel to the second plane (24, 164, 214).</p> |
