  • Elasto-plastic springback of beams subjected to repeated bending/unbending histories
    Kosel, Franc ...
    This contribution investigated repeated elastoplastic pure plane bending/unbending process of beams made of material with an elastic-linear hardening rheological model. The attention is focused on ... beams with cross sections which have at least one axis of symmetry and are initially straigh orhave constant radius of curvature. Elastoplastic deflection states of beams after repeated bending/unbending process are determined using the large displacement theory. Experiments were conducted to verify the theory for beamsmade of aluminium alloy AA 5050-H38 with rectangular cross sections. It is shown that maximal relative difference between experimental and theoreticalresults in the case of a largely curved beams after repeated bending/unbending process is 1.27%.
