Claim:
An extensometer body, comprising: (a) a first body part having a long axis, and a short axis, the short axis transverse to the long axis, the first body part having at a first end of its long axis an opening configured for attaching a first end of a linear variable differential transformer and at a second end of its long axis an opening configured for attaching a first specimen contact rod; (b) a second body part having a long axis parallel to the first body part long axis and a short axis parallel to the first body part short axis, the second body part having at a first end of its long axis an opening configured for attaching a second end of the linear variable differential transformer and at a second end of its long axis an opening configured for attaching a second specimen contact rod; (c) a thin flexure body part positioned between the first and second body parts having a long axis parallel to the short axis of the first and second body parts and bridging the first and second body parts together into a single piece capable of relative movement between the first and second body parts generally only in rotation about the long axis of the thin flexure body part; and, (d) wherein the thin flexure body part is longitudinally spaced between the first end of the long axis of the first body part and the second end of the long axis of the first body part, and wherein the thin flexure body part is also longitudinally spaced between the first end of the long axis of the second body part and the second end of the long axis of the second body part.
