Abstract
A tensile test fixture for applying constant tensile forces to a tensile test specimen comprises two mounting grips, each mounted to one of two lever arms in a pivoted lever arm frame structure. One end of each lever arm is pivotally attached to a compression column while the other end of each lever arm is attached to one end of a force-applying assembly. The mounting grips are pivotally attached to their respective lever arms between the compression column and the force-applying assembly and are designed to hold opposite ends of a tensile test specimen. The force-applying assembly comprises stress and strain modules that are interchangeably installable into the force-applying assembly to selectively subject tensile test specimens to constant strain and constant stress.
