Spišák NUMERICAL AND EXPERIMENTAL SPRINGBACK DETERMINATION OF SHEET METALS IN AN AIR BENDING PROCESS Abstract This paper dealt with experimental and numerical springback determination of sheet metals in an air bending process. Practical part of paper consists of two sections. The first part dealt with experiment of air bending process of three different categories of steel, different bending depths and die widths. Influence of these technological variables is discussed. Paper uses a modern measurement method performed in MATLAB. Second part consists of numerical simulation of air bending process in explicit and implicit finite element method (FEM) code. Hill’ 48 yield criterion and Hollomon (Ludwik) hardening law were set as material model used in numerical simulation. In this paper are compared two different finite element (FE) codes from the accuracy point of view.
