Abstract
Novel markers that can be attached physically to a tensile specimen with a center guide to allow for measuring correct strain, as well as a binder that fixes and holds a pin guide to its location on the specimen during the test.
Claims16
A system for measuring strain comprising:
- a tensile specimen marker for use on a tensile specimen, the tensile specimen marker comprising;
- a first arm, a second arm, and a spring connecting the first arm to the second arm;
- wherein the first arm removably attaches to a first side of a tensile specimen;
- wherein the second arm removably attaches to a second side of the tensile specimen;
- wherein the first arm comprises a marker configured to define a position on the tensile specimen;
- wherein at least two tensile specimen markers are attached to the tensile specimen using a ruler to specify a distance between the at least two tensile specimen markers on the tensile specimen;
- and
- wherein the ruler holds more than the at least two tensile specimen markers to provide for placing more than two markers at more than two locations on the tensile specimen to allow for measuring transvers strain in addition to vertical strain.

A method for measuring strain comprising:
- providing a tensile specimen;
- applying at least two of removable markers to the tensile specimen;
- measuring strain between the removable markers;
- wherein the at least two removable markers are attached to the tensile specimen using a ruler to specify a distance between the at least two removable markers on the tensile specimen;
- and
- wherein the ruler holds more than the at least two removable markers to provide for placing more than two markers at more than two locations on the tensile specimen to allow for measuring transvers strain in addition to vertical strain.
