Influences of material dilatancy and pore water pressure on stability factor of shallow tunnels YANG Xiao-li(杨小礼), HUANG Fu(黄 阜) School of Civil and Architectural Engineering, Central... support in limit state. The proposed method was formulated within the nonassociative plasticity. For the shallow tunnels in soft clay, without considering the influences of pore water pressure......
Residual stress relaxation in typical weld joints and its effect on fatigue and crack growth Chunyan JI1,Zhengquan WAN2,Liangbi LI1,Zili WANG1 (1.School of Naval Architecture and Ocean Engineering... for predicting the residual stress at hot spot quantitatively is proposed. Based on the formula, an improved fatigue procedure is introduced. Moreover, crack growth of typical weld joints considering......
Mechanism of effect of rare earth oxides on high temperature corrosion resistance of weld metal LI Zhi-yong(李志勇)1, WANG Bao(王 宝)1 , ZHANG Han-qian(张汉谦)2 1. College of Materials Science... Abstract: Through the addition of rare earth oxides into the coating of electrodes, the high temperature oxidation and sulphidation resistance of weld metal were studied. The transfer mechanism......
