Sažetak
In order to determine the inevitable mechanical springback of a bended plates, designed for assembling the spherical tanks an elastic-plastic incremental finite element calculation has been carried out to analyse axisymmetric strain sheet metal bending process. Sufficiently accurate stress distributions and deformed geometry of plates as parts of spherical tanks have been obtained through the whole bending process. The load-deflection curve has been carried out based on reaction forces and compared with experimentally obtained results. Friction effects and material characteristics such as work hardening are also covered. The accuracy of the simulation results, mechanical springback and the residual stress distribution after unloading are discussed through the comparison with the experimental results.
