A novel tensile stress relaxation test has been developed. It measures the residual stress in slender specimens mounted on a simple test frame by creating a small bowstring-like movement and measuring the force required to do so. Unlike the commoner compression tests, it permits a high ratio of exposed surface to volume to be maintained in the specimens, facilitating study of environmental effects. It also avoids suppression of any effects where progress of surface cracking might play an important part. The accuracy of the test is estimated at ±5% and, unlike simple tensile tests, would suffer no further deterioration from friction or adhesion of frame components. The test is cost-effective and the frames can operate in a wide range of temperatures and environments.
