tensile stiffness on the critical height ratio, stress concentration ratio, soil arching ratio, geosynthetic tension and axial strain were investigated. This study suggests that a RPC of 1:1.0 and a one-way...; (10) where a is the pile cap width; q0 is the uniform surcharge on the embankment top. Then, the stress concentration......
UV-Vis Spectroscopy Study on Interaction between Microperoxidase-11 and Pr Ion Under Acid Rain Stress 周青1,吉红念2,陆天虹3,黄晓华3 (1.School of Biotechnology, Southern Yangtze University, Wuxi 2140366, China... in living organism. H+ and Pr(Ⅲ) have antagonistic effect on MP11, suggesting that at suitable concentration under physiological conditions, Pr(Ⅲ) can be used as biomodulator in protecting plants......
. The hydrogen diffusion without the effect of stress was also calculated and compared. Owing to the existence of welding residual stress, the hydrogen concentration was obviously increased and the hydrogen...3-D FINITE ELEMENT ANALYSIS OF THE EFFECT OF WELDING RESIDUAL STRESS ON HYDROGEN DIFFUSION IN HYDROGEN CONTAINED ENVIRONMENT H.

Effect of Boron Concentration on Dynamic Recrystallization Behavior of Low-Carbon SteelYong-Liang Gao,Xiang-Xin Xue,He YangLiaoning Key Laboratories of Ecological Utilization Technology of Boron... s-1,and inspection of the initial austenite grain size at 1150 °C.The resulting stress–strain curves are observed to possess two classifications of behavior,dynamic recovery and dynamic......
160 h when the alloy was crept at 700 ℃ and 300 MPa. The stress concentration and consequently crack nucleation and propagation are the main reason for failure of the alloy. When the stress decreases, the stress concentration is released by the grain rotation. It inhibits the crack nucleation and thus extends the alloy rupture life obviously. However, accompanied with the grain deformation......
