Experimental and numerical study of the response of steel sheet Hopkinson specimens

The structural diaphragm effects have been investigated in the past decades with major attention on the properties of diaphragm panels. The research observations made by the oversea researchers cannot be directly utilized to the design construction of Chinese light gauge steel structures due to the different configuration of profiled steel sheets, fasteners, and purlins in China. In this regard, the shearing strength and stiffness of diaphragm steel sheets are investigated in this study through numerical study. The profiled steel sheet and fastener are simulated by the ortho-anisotropic flat plate and three one dimensional nonlinear spring, respectively. The analytical models are developed for examining the shearing strength and stiffness induced by diaphragm effects of a cladding system. The made observations indicate that the diaphragm effects of the steel sheet on the structure are obvious.

Abstract In brazing, the interfacial conditions between the molten filler material and the solid workpiece are important, yet they cannot be observed experimentally. A two-dimensional axisymmetric simulation was conducted to analyze the behavior of a single droplet of molten aluminum on zinc-coated steel sheet as a simplified brazing process. The simulation models were verified through a comparison with experimental results in terms of bead shape, zinc distribution, and molten metal behavior. The results show that Young’s equation was not valid in explaining the wetting behavior because of the instant solidification. In this respect, the effects of the workpiece thickness and wetting angle on the bead width were negligible. Two periods of time, namely the times for the temperature difference and solidification, and their ratio (interface number) were defined to analyze the temperature behavior at the interface over time as well as the effects of workpiece thickness. The interfacial temperature behaviors tended to be divided into three regions: linear (or inversely proportional), singular, and convergence. The interface number converged to a value of one with the increase in the thickness.
