Abstract

A method for testing the mechanical properties of a specimen. The specimen is generally characterized by a first contact surface and a second contact surface spaced apart from and opposing the first contact surface. The method involves applying forces to the contact surfaces of the specimen to deform the specimen over a period of time. The response of the specimen to the forces is then measured over time. A spatial distance between the contact surfaces is defined such that the equivalent gauge length of the specimen is greater than the distance between the contact surfaces.
