Effect of displacement velocity on elastic plastic

The elastic-plastic fracture toughness, J Ic, of SM490B carbon steel plate was investigated in air and 0.7 MPa hydrogen gas.J Ic tests were conducted in accordance with the JSME standard, JSME S001 (1981). J Ic was much smaller in hydrogen at a displacement velocity of V = 2 × 10-3 mm/s (J Ic = 10.0 kJ/m 2) than in air at V = 2 × 10-3 mm/s (J Ic = 248.6 kJ/m 2). Effects of Cyclic Plastic Strains on Fracture Toughness of Jan 01, 1998 · The maximum strains 0.5 % and 1.0 % and the repeated loading of 0.5, 3, 5.5 and 10.5 cycles were considered. As an example, Fig. 3 shows load versus strain curves for the top and bottom flanges of the test beam with the maximum strain 0.5 % and the repeated loading of 10.5 cycles. When the flange is in the lower side, the load is represented with the plus sign.

Fatigue Life Properties and Anomalous Macroscopic Fatigue Dec 01, 2016 · In SM490B steel, this general fracture process was confirmed in air and 0.7 MPa hydrogen gas. In contrast, in 115 MPa hydrogen gas, there was no tilted portion in the stage III region, and the fracture surface was totally flat. Fire-Resistant Steels:Part Two ::Total Materia ArticleThe yield strength was measured at 0.2% strain offset from the temperature-stress-strain curves. Although there is a large discrepancy between the test results, all FR steels are in the range of 2/3 yield strength at ambient temperature at 600°C. Figure 1:Strength reduction factors for yield strength of FR steel at elevated temperatures.

Slow strain rate tensile and fatigue properties of CrMo May 04, 2015 · In JIS-SM490B tested in hydrogen gas, relatively large surface cracks were observed (e.g., 100 m in length). These were not only in the necked region, but also in the un-necked region. However, such a large crack was not observed at the surface of the specimen tested in nitrogen gas.
