NUMERICAL AND EXPERIMENTAL FORMING OF AXISYMMETRIC PRODUCTS USING METHODS OF DEEP DRAWING AND FLOW FORMING

The paper deals with the problem of forming of axisymmetric element. Two-stages process was taken into consideration: deep drawing of metal blank using hydraulic press and the method of elongating flow forming. The contribution presents results of numerical and experimental analyzes. Numerical simulations of both the processes were realized in Krakow at AGH University. Numerical verification of both processes was carried out using finite element models implemented with the help of commercial analysis system on basis of conducted in Poznan experimental shaping tests of Hastelloy C-276 alloy. The tests were aimed to find opportunities and conditions of plastic deformation of the material. This article summarizes example results of both numerical and experimental forming of products made of hard-to-deform material..
