A novel tensile stress relaxation test: development and applications to a study of non-rubber constituents and fillers in natural rubber
thesis
posted on 2017-10-09, 11:22 authored by Alias B. OthmanA 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. [Continues.]
