WebTo study the variation of rock burst proneness according to different strain rates, four strain rates (0.005, 0.01, 0.5, and 1.0 s −1) were considered based on the typical range of strain rate ε e associated with rock burst (Wasantha et al., 2015).The specific test plan is listed in Table 1.Moreover, to avoid the heterogeneity of the rock material (especially the layered … WebFrom National Research Council Canada. High-speed uniaxial compression tests were conducted in the strain-rate range 10-1-101 s-1, at -11 C, on freshwater ice and "Baltic" …
Impact Compression Test of Ice by Combining SHPB …
WebJul 8, 2024 · The fracture behavior and stress of ice at high strain rates can be determined by combining the SHPB method with high-speed camera observation. The split Hopkinson pressure bar (SHPB) method proposed by Kolsky [ 1, 2] is the most famous impact test to measure the deformation of materials under high strain rates. WebApr 2, 2007 · The compressive strength of ice was measured at high strain rates of 103s−1 order of magnitude. Since ice compressive strength is known to be strongly dependent on strain rate,... flagship hotel ac

WebApr 1, 2007 · The compressive strength of ice was measured at high strain rates of 103 s−1 order of magnitude. Since ice compressive strength is known to be strongly dependent on strain rate, properties corresponding to high strain rates are needed for engineering predictions of the behavior of ice under dynamic crushing scenarios. The split Hopkinson … WebThe SHPB was adapted to perform tests at high strain rates in the range 60 to 1400/s at test temperatures of -10 and -30 C. Experimental results showed that the strength of ice … WebDec 1, 2006 · Schulson (2001) (see Fig. 2) shows a dramatic increase for polycrystal ice in the compressive failure stress from 0.5 MPa at a strain rate of 10 −8 s −1 to 10 MPa at a strain rate of 10 −3 s −1 then a decline to 6 MPa at 10 −1 s −1 (with considerable scatter in the data).
