Understanding Strain-Rate Sensitivity In Polymers

WebbUniaxial tensile tests were performed at the moderately high strain rate of approximately 10% per second with a servo-hydraulic testing machine. This represented a strain rate that was approximately 100 to 1000 times faster than that previously reported. Webb7359-7 [17] standards, and can be broadly described as a tensile experiment conducted using a slow, but constant extension rate (which typically yields an initial strain rate <10 5 s 1) while the specimen is exposed to the envi-ronment of interest [18, 21, 22]. Numerous changes to this basic framework have been employed in the literature [14, 21]. Webb29 juli 2016 · Tensile tests were performed on a PP material at the same temperature using three different strain rates, indicated by the speed at which the crosshead of the tensile tester moved.
