composite structure with overlap slab of Xingguang bridge YE Mei-xin(叶梅新), HUANG Qiong(黄 琼), WU Qin-qin(吴芹芹) (School of Civil and Architectural Engineering, Central South University, Changsha 410075, China) Abstract: Finite element modeling methods of steel-concrete composite structure with overlap slab were investigated. A two-step finite element method was presented. It was applied to analyze......
friction stirring. Also, bend testing shows that, the cladded joints exhibit excellent ductility. Key words: friction stir cladding; dissimilar joint; overlap ratio; optimization 1 Introduction Magnesium... lap welding to clad aluminium sheet on magnesium plates, overlap area between two seams is an important factor, which decides the joint integrity. Hence, tool rotational speed, welding speed......
Effects of the types of overlap on the mechanical properties of FSSW welded AZ series magnesium alloy jointsDan Wang,Jun Shen,and Lin-zhi Wang School of Materials Science and Engineering,Chongqing University,Chongqing 400044,China摘 要:The effects of the types of overlap on the mechanical properties of the friction stir spot welding(FSSW) welded AZ series......
plane; similar integrity shear failure. The inclination angle has a decisive effect on the failure mode of the specimen, and the joint overlap affects the growth of the specimens’ crack. 2) The peak... overlap. The peak of shear strength is more sensitive to the joint inclination. 3) The difference of shear stress-displacement curve for different inclination is mainly reflected in the post-rupture......
