Slow Strain Rate Tensile Test and Fracture Surface Observation The tensile test was carried out in air or in 70 MPa hydrogen gas while keeping the strain rates at 5.0 × 10−5, 7.5 × 10−6, and 1.25 × 10−6 s−1, with the test temperature at ...
Webb15 dec. 2024 · Slow Strain Rate Tensile (SSRT) Tests SSRT had been evaluated at room temperature on a Xi’an LETRY stress-corrosion cracking tester manufactured by a Chinese provider. Tensile specimens with dimensions of 140 mm gauge in length and 30 mm gauge in width were machined from the TAM steel sheets paralleling to rolling direction. Webb1 mars 1992 · Briefly, the SSR technique involves the slow straining of a specimen of the alloy of interest in a possible cracking environment. Typically, a strain rate of the order of 10?6 s?1 is used, which is about four orders of magnitude slower than that used in a standard tensile test.

WebbEzio Cadoni. 2013, Magazine of Concrete Research. Direct tensile tests on cubic concrete specimens of 60 mm side were performed at strain rates from 1 s−1 to 10 s−1 by means of a modified Hopkinson bar. The results of 26 such high strain rate tests on two concrete types, with 5 and 10 mm maximum aggregate size, are presented in this paper. diamond arbiter crossword clueWebbIt can perform Slow Strain Rate Tests (SSRT), Constant Load (CL) tests and Low Frequency Cyclic Fatigue (LFCF) tests. The loading device can be used in ambient temperature, autoclave and high temperature gas environments. There are several models available of which the 25 kN and 50 kN instruments are the most popular. circle k mallard creekWebbConventional tensile testing is done at strain rates slow enough to be called “quasi-static.” These rates are several orders of magnitude slower than the deformation rates during … circle k market capWebb7359-7 [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]. diamond a ranch lipan texasWebbUniaxial tensile tests were performed at the moderately high strain rate of approximately 10% per second with a servo-hydraulic testing machine.
