“…Finite element methods were used to generate training data for neural network. Besides single bending/unbending processes, complex bending histories, like double-bend technique, are also frequently encountered in die-forming processes ( Ref 7,[20][21][22][23] and are generally more difficult for theoretical study.…”

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 straight or have 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 beams made of aluminium alloy AA 5050-H38 with rectangular cross sections. It is shown that maximal relative difference between experimental and theoretical results in the case of a largely curved beams after repeated bending/unbending process is 1.27%.
