J. Cent. South Univ. (2016) 23: 1293-1300 DOI: 10.1007/s11771-016-3179-9 Effect of Nb content on microstructure stability and stress rupture properties of single crystal superalloy containing Re..., 1.0%Nb were cast in the directionally solidified furnace, while other alloying element contents were basically kept unchanged. The effect of Nb on the microstructure, stability at 1100 °C and stress......

segments among joints in the inner zone,and develop towards both the opening and the neighboring joints (see Fig. 6(b)). The excavation induces stress concentration in the Inner zone around the opening...J. Cent. South Univ. (2017) 24: 2406-2420 DOI: https://doi.org/10.1007/s11771-017-3652-0 Failure behavior around a circular opening in a rock mass with non-persistent joints: A parallel-bond stress......
discontinuity of the von Mises stress curves, which leads to the intensive stress concentration on the coating/substrate interface. So the coating configurations with the larger coating thickness and lower... and interface stress of thick coatings are both comparatively low. The status of stress concentration and plastic yield in thick coatings may be slight under the identical loading condition, so, the thick......
ends. The stress concentration occurs in the roofcenter, and the maximum bending moment Mmax appears in the central area of the roof rock. The extreme value, Mmax, of M(x) can be presented as: ... is the standard value of high stress load, and generally the value is 10 kN/m2; l is the stope span. Under the action of high stress, the stress concentration occurs in the roof of the stope. With the increasing......

Distribution of sodium concentration in cathode carbon blocks was calculated by one FE model of a cathode... calculation. A linear relationship between sodium expansion stress and sodium concentration of the anthracitic carbon was investigated and found by ZOLOCHEVSKY et al[10-11]. Pure graphitized carbon......
enzymes in leaves were assayed. The results show that the treatment with appropriate concentration of LaCl3 has resistant effect on oxidative stress induced by 2, 4-D. Proper concentration of LaCl3...Resistance of LaCl3 to Oxidative Stress Induced by 2, 4-Dichlorophenoxy Jia Yanxia1,Gao Yongsheng1,Zeng Fuli1 (1.School of Life Science, Lanzhou University, Lanzhou 730000, China) Abstract......
