Steel-concrete composite slabs with cold-formed, profiled steel deck sheets are popularly used in steel-framed buildings. In these slabs, the platform acts as a working during construction and also tensile reinforcement under in-service load conditions. The shear bond capacity of slab is evaluated this study for two different profile sheets. Specifically, their behaviour investigated by casting...

Because of the need for weight reduction in transport industry, in order to save energy as well as to reduce CO2-emission, the use of light weight aluminium sheet is taken increasingly into consideration [1]. But although aluminium is lighter than steel, the formability is less, hence press operations are often more critical. Alloys used are typically 5xxx alloys for inner panels because of the...

Steel laser tailor-welded blanks (TWBs) are produced by end-to-end joining of base sheets using different welding methods. In this article, the formability of laser TWBs of St12 and St14 with thicknesses of 1 mm and 1.5 in single point incremental forming process were experimentally and numerically investigated. First, the forming limit wall angle was experimentally determined for each of the b...

Equal channel angular rolling (ECAR) process is one of the severe plastic deformation (SPD) methods that have been used to make ultra-fine grain (UFG) materials with improving the mechanical properties of samples. After performing the process at several paths, a large strain is applied to the material that can cause decreasing the grain size and improving the mechanical and physical properties ...
