Increasing of strain rate during forming of semi products or products is one of the ways of production intensification. Therefore an attention is paid to the study of the influence of the strain rate on the material behaviour in the deformation process, but also on the methodology of evaluation of formability at increased strain rates (including impact) 1,2 . In general, it applies that increas...

Suspensions of the faecal indicator bacteria Escherichia coli and Enterococcus faecalis were incubated in full sunlight in plastic bottles containing either (i) air-equilibrated (oxygenated) water or (ii) anaerobic (deoxygenated) water. A rapid decrease in cfu ml-1 was observed for actively growing and stationary phase cells of both types of faecal bacteria when illuminated under aerobic condit...

electromagnetic forming is a high energy rate forming process. in this process, an electromagnetic lorentz body force is used for deformation of products. in this article, electromagnetic forming process was simulated for assembly of parts as an innovative method. in this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...

Fiber reinforced plastics (FRPs) are increasingly being used to reinforce the steel or aluminum automotive structure components. Currently, these multi-material applications realized in general by a multi-stage manufacturing with considerable cost increase. To avoid this, new hybrid forming method has been proposed and developed. It uses half liquid FRP as pressure media hydro-form sheet metals...

Bioplastics have proven to be a viable substitute for plastics in some sectors, although their use construction is still limited. The sector currently uses 23% of the world’s plastic production, both materials themselves and packaging protection. A considerable part not recycled dispersed into environment or ends up landfills. In response environmental problems caused by oil-based pollution, de...

Fiber-reinforced plastics (FRP) production in many cases involves expensive molds, which especially hinders cost-effective of small series and prototypes. In metal parts production, incremental sheet forming (ISF) is an established process for creating individual through a flexible die-less process. Establishing similar FRP desirable but challenging, as deformation mechanisms endless differ sig...
