Реферат: An algorithm for solving an inverse problem of forming a ribbed panel made of the AK4-1 alloy (analog of the AA2018 and Al-Cu2-Mg2-Ni1 alloys) at a temperature of 200◦C is proposed. The problem is reduced to solving a sequence of auxiliary direct problems on the stress-strain states of the elements of the panel structure. The structural elements are taken to be T-beams sub- jected to pure bending. The resultant moment for obtaining a desired shape is calculated by the Nelder–Mead simplex algorithm. Two approaches to obtaining goal-shaped parts are considered: deformation under the plastic flow condition and under the creep condition. The material models used in the study take into account the difference in the mechanical properties under tension and compression, as well as the presence of damage accumulated in the material. The calculations are performed with allowance for elastic springback of the part after load removal.
